1.2 Safety Information
Use this instrument only as specified in this manual. Otherwise, the protection
provided by the instrument may be impaired. Refer to the safety information in The
following sections.
The following denitions apply to the terms “Warning” and “Caution”.
● “Warning” identifies conditions and actions that may pose hazards to the user.
● “Caution” identifies conditions and actions that may damage the instrument
being used.
1.2.1 Warnings
● DO NOT use this unit in environments other than those listed in the User’s
Guide.
● Follow all safety guidelines listed in the User’s Guide.
● Calibration equipment should only be used by trained personnel.
● This instrument can measure extreme temperatures. Precautions must be taken
to prevent personal injury or damage to objects. Probes may be extremely
hot or cold. Cautiously handle probes to prevent personal injury. Carefully
place probes on a heat/cold resistant surface or rack until they reach room
temperature.
● If this equipment is used in a manner not specied by the manufacturer, the
protection provided by the equipment may be impaired.
● Before initial use, or after transport, or after storage in humid or semi-humid
environments, or anytime the instrument has not been energized for more than
10 days, the instrument needs to be energized for a “dry-out” period of 2 hours
before it can be assumed to meet all of the safety requirements of the IEC
1010-1. If the product is wet or has been in a wet environment, take necessary
measures to remove moisture prior to applying power such as storage in a low
humidity temperature chamber operating at 50 °C for 4 hours or more.
● The AC adapter can present safety concerns if misused or damaged. To avoid
the risk of electric shock or re, do not use the AC adapter outdoors or in a
dusty, dirty, or wet environment. If the cord, case, or plug of the adapter is
damaged in any way, discontinue its use immediately and have it replaced.
Never disassemble the AC adapter. Use only the AC adapter provided with the
instrument or equivalent adapter recommended by the manufacturer of this
instrument.
● The AC adapter has circuits with high voltage inside that could present danger
of electrical shock or re if exposed. If the AC adapter is damaged in any way
or becomes hot, discontinue its use immediately, disconnect it from any AC

supply, and have it replaced. Do not attempt to open, repair, or continue using a
damaged or defective AC adapter.
● The instrument batteries can present danger if not handled properly. To avoid
the risk of exposure to dangerous substances or explosion, immediately remove
the batteries and discontinue use if they leak or become damaged. Never allow
the batteries to be shorted, heated, punctured, or dropped. If the instrument is
physically damaged, immediately remove the batteries to insure that they do
not become shorted. While removed from the instrument, store the batteries in
a location so that they do not come into contact with metal or uids that might
short circuit the batteries and where they are safe from excessive temperatures.
Used batteries must be disposed of properly. Check your local regulations for
additional information. Never dispose of batteries in re which may result in
explosion with the possibility of personal injury or property damage.
● DO NOT use this instrument in combination with any probe ( PRT, thermistor,
or thermocouple) to measure the temperature or resistance of any device where
the probe might come in contact with a conductor that is electrically energized.
Severe electric shock, personal injury, or death may occur.
1.2.2 Cautions
● If the instrument is dropped, struck, or handled in a way that causes internal
or external physical damage, immediately unplug the AC adapter, remove the
batteries, discontinue use, and contact the factory for repair. Do not attempt to
disassemble or repair the instrument, batteries, or AC adapter. Refer repairs or
replacement components to the manufacturer.
● The instrument and thermometer probes are sensitive and can be easily
damaged. Always handle these devices with care. DO NOT allow them to be
dropped, struck, stressed, or overheated.
● Probes are fragile devices which can be damaged by mechanical shock,
overheating, and absorption of moisture or uids in the wires or hub. Damage
may not be visibly apparent but nevertheless can cause drift, instability, and loss
of accuracy. Observe the following precautions:
● DO NOT allow probes to be dropped, struck, bent, or stressed.
● DO NOT overheat probes beyond their recommended temperature range.
● DO NOT allow any part of the probe other than the sheath to be immersed in
uid.
● DO NOT allow the probe hub or wires to be exposed to excessive temperatures.
● Keep the probe wires clean and away from uids.

1The sensor generally limits the actual temperature range. Temperature accuracy specifications do not
include sensor accuracy. Thermistor temperature accuracy assumes a 10kW sensor. Thermocouple
accuracy is with internal reference junction compensation; accuracy is improved with external reference
junction compensation. Thermocouple temperature accuracies are given for external reference junction
compensation and internal reference junction compensation, respectively.
2Measurement accuracy specifications apply within the operating temperature range and assume 4-sample
averaging and 4 lead wires for PRTs. With 3-wire RTDs add 0.05W to the measurement accuracy plus the
maximum possible difference between the resistances of the lead wires.
3Actual resolution can be set greater than typical resolution, but the added digits (0.0001 max.) may not be
meaningful to the measurement.
2.2 Environmental Conditions
Although the instrument has been designed for optimum durability and trouble-free
operation, it must be handled with care. The instrument should not be operated in an
excessively dusty, dirty, or wet environment. Maintenance and cleaning recommenda-
tions can be found in Section 9, Maintenance on page 123.
For full accuracy, operate the instrument in ambient temperatures between 16–30 °C
(61–86 °F). The battery may not charge properly at temperatures above 30 °C. Do
not operate the instrument in an environment colder than 5 °C (41 °F) or warmer than
40 °C (104 °F).
The instrument operates safely under the following conditions:
● Ambient temperature range: absolute 5–40 °C (41–104 °F) [full accuracy 16–
30 °C (61–86 °F)]
● Ambient relative humidity: maximum 80% for temperature <31 °C, decreasing
linearly to 50% at 40 °C
● Pressure: 75 kPa–106 kPa
● Vibration should be minimized
● Altitude less than 2,000 meters
● Indoor use only

If all items are not present, contact an Authorized Service Center (see Section 1.3,
Authorized Service Centers on page 4)
3.2 Use Proper Care
You must understand the safety issues related to the 1529. Be aware that potential haz-
ards exist due to high temperatures and battery chemicals. Carefully read the Warnings
and Cautions in Section 1.2, Safety Information on page 3.
The 1529 and any thermometer probes used with it are sensitive instruments that can
be easily damaged. Always handle these devices with care. DO NOT allow them to be
dropped, struck, stressed, or over-heated.
3.3 Learn About the Features and Components
Familiarize yourself with the features and accessories of the 1529 by reading Section
4, Parts and Controls on page 13.
3.4 Connect the Probe
The PRT/thermistor or thermocouple probe connects on the back panel of the 1529
using patented mini-DWF connectors (PRT/thermistor) or the universal receptacles
(thermocouples).
3.4.1 Using the Clamp-on Ferrites
Clamp-on ferrites are provided with this product for the use of improving its electro-
magnetic (EM) immunity in environments of excessive EM interference. During EMC
1529 Chub-E4 Thermometer Readout
Connect the Power Source
10
testing we found that ferrites clamped around the probe cables and power cord reduced
the risk that EM interference affects measurements. Therefore, we recommend that
the clamp-on ferrites provided (Steward P/N 28A2025-0A2) be used on the cables of
probes attached to this product, especially if it the product is used near sources of EM
interference such as heavy industrial equipment.
To attach a ferrite to a probe cable, make a loop in the cable near the connector and
clamp the ferrite around half of the loop as shown in Figure 1 on this page The ferrite
can be easily snapped open and moved to a new probe when needed.
Figure 1

3.5 Connect the Power Source
The 1529 draws power from either a 15-volt DC power supply (the included AC
adapter) connected to the DC input or the internal re-chargeable battery pack. To use
the AC adapter, plug it into a wall outlet of the appropriate voltage and insert the DC
plug into the DC power input of the 1529 (see Figure 3 on page 14).
3.6 Switch the Power On
Power is turned on and off with the power switch located on the top right corner of
the back panel. To switch the power on, toggle the power switch to the ‘ON’ position.
To switch power off, toggle the power switch to the ‘OFF’ position. The instrument
takes a few seconds to power up, initialize, and begin normal operation. A self-test is
performed displaying the channel conguration and status of the system, calibration,
GPIB, memory, and buttons. If the thermometer readout calibration has expired, the
user is notied and must press the Enter button to continue initialization. If an error
message is displayed on power up see Section 10, Troubleshooting on page 125.
3.7 Measure Temperature
After initialization, the temperature measurements for the congured channels are dis-
played. The appropriate sensor type must be selected and coefcients entered for the
measurements to be accurate (see Section 6.2.1, Edit Probe on page 30). Place the sen-
sors of the probe into the object(s) you want to measure. DO NOT force the probe(s)
or otherwise allow them to be bent, stressed, or overheated. Probes can be easily dam-

5 General Operation
This section explains basic operation of the 1529 thermometer readout. Detailed op-
eration of the 1529 is explained in Sections and . Section explains the menu structure
and the functions available in the menu structure and Section explains the communi-
cations interface for operating the 1529 remotely.
5.1 Display
The 1529 display consists of two parts. The top portion of the display is used for
displaying the measurements from one to four inputs. The bottom portion of the dis-
play is reserved for the programmable elds and eld display sets. Information about
the channels and measurements can be displayed in greater detail such as min, max,
spread, standard deviation, and many other functions. When the measure period is 0.1
or 0.2 seconds (fast measurement mode), the programmable elds and eld display set
information are not displayed.
5.2 Changing Units
The 1529 thermometer readout is capable of displaying temperature in Celsius (C),
Fahrenheit (F), or Kelvin (K). (Displaying in units of W, KW, or mV is also available
through the PROBE menu and is channel specic.) Temperature units are changed on
all channels (not individually) by pressing the buttons on the front panel when not in
the menu structure. Press the Unit, LR, buttons to scroll forward and backward
through C, F, or K. All channels or elds that are displaying temperature on the upper
or lower display are updated to the new units.
Channels that are set to W, KW, or mV in the PROBE menu are left unchanged when
temperature units are modied. Changing the units resets the statistical calculations
(displayed in the bottom portion of the display).
5.3 Battery
The 1529 thermometer readout has a built-in nickel-metal-hydride battery pack that
can power the instrument for about eight hours before needing to be recharged. The
battery discharges more quickly when the display backlight is used. The percent of
battery charge remaining is displayed on the bottom portion of the display when the
battery power is being used. The battery percentage is approximate and should only be
used as a general guideline when determining the length of charge remaining. The bat-
tery is recharged in situ (while in place) using the AC adapter that is provided.
Plug the AC adapter into the wall outlet and connect the DC plug of the adapter
into the 1529. The battery is charged as necessary whether or not the instrument is
switched on. The power control circuit inside the instrument manages battery charging
and stops charging the battery automatically when the battery is fully charged. Only
charge the battery when ambient temperature is between 16 °C and 30 °C (61 °F and
86 °F) It normally takes about three hours to fully charge the battery. The instrument
can be operated while the battery is being charged. The charging indicator on the back
1529 Chub-E4 Thermometer Readout
Probe Input Modules
18
panel is green when the battery is fully charged and amber when being charged using
the AC adapter.
The battery may self-discharge over several months, especially if the temperature is
warm. The battery pack can be used for a minimum of 500 charge-discharge cycles be-
fore needing to be replaced. Replacement battery packs are available from the manu-
facturer. The battery pack can be easily removed and replaced in the eld by following
this procedure:
1. Power the 1529 off and unplug the AC adapter from the unit.
2. Turn the 1529 over to expose the battery compartment. Remove the battery
cover hex screw. Place the screw in a safe place so it won’t get lost. Flip open
the battery cover to reach the battery pack.
3. Remove the battery pack. Gently disconnect the battery plug connector.
4. Attach the polarized plug of the new battery pack onto the connector. Note: The
battery plug is polarized and can only be plugged in one direction. DO NOT
force it. Place the battery pack in the battery compartment.
5. Close the battery cover and replace the screw. Avoid pinching the battery wires.
6. Plug in the AC adapter and charge for a minimum of four hours for the
initial charge. Used batteries must be disposed of properly. Check your local
regulations for additional information. You may return used batteries to
the manufacturer. Never dispose of batteries in re as this may result in an
explosion with the possibility of personal injury or property damage.
When the battery charge is not at 100%, the measurement accuracy is not affected. If
the power is interrupted while the instrument is logging measurements (on demand or
automatically), the logged data is preserved and logging resumes when the power is
restored.
5.4 Probe Input Modules
The 1529 can be congured in three ways:
● Two RTD/thermistor input modules.
● Two thermocouple input modules.
● One RTD/thermistor and one thermocouple input module.
Each input module supports two channels. Your 1529 thermometer readout is cong-
ured at the factory and is not eld changeable. Input modules should never be removed
for any reason.
All possible congurations are shown in Figure 3 on page 14.
5.4.1 Connecting a PRT or Thermistor Probe
PRT and thermistor probes are attached to the resistance input module via Hart Sci-
entic mini-DWF connectors. These patented connectors accept bare wire, spade, or
mini banana plug terminations. The connectors are color coded for ease in connecting
lead-wires.
19
General Operation
Probe Input Modules
When using 2- and 3-wire sensors, the accuracy of the 1529 is reduced as stated in
the specications. Compensation is made for 3-wire PRTs, but the difference in lead
resistance affects the measurement accuracy. The 1529 thermometer readout is unable
to compensate for 2-wire lead resistance.
Attach the lead-wires of the probes as shown in Figure 4 on this page. The top ter-
mainals sense current and the bottom terminals sense potential.

5.4.2 Connecting a Thermocouple
The 1529 thermocouple input module accepts both standard and sub-miniature size
thermocouple connectors. The connection is made with the positive terminal on the
right and the negative terminal on the left. You must use a connector that matches the
thermocouple type for the internal RJC to be accurate. For example, if you are using
a type K thermocouple you must also use a type K connector, which is made from the
same type of metal. For best results, wait two minutes before measuring after inserting
the thermocouple connector into the input module.
Figure 5 Thermocouple Connections
5.5 DC Power Source
Caution: For CE compliance and for performance, use only the AC adapter
shipped with the instrument by Hart Scientic. If the AC adapter needs to be re-
placed, contact an Authorized Service Center (see Section 1.3, Authorized
Service Centers on page 4).
The DC power source provides power to charge the battery. It can also be used to pow-
er the 1529 while the battery is being charged. The AC adapter provided with the 1529
is intended for these purposes. The DC power source plugs into the DC power input
on the back panel of the instrument. The AC adapter has circuits with high voltages
inside that could present danger of electric shock or re if exposed. If the AC adapter
is damaged in any way or becomes hot, discontinue use immediately, disconnect the
adapter from any AC supply, and replace the adapter. Do not attempt to open, repair, or
continue using a damaged or defective AC adapter.
21
General Operation
Taking Measurements
5.6 Power On Self-Test
When power is turned on, the 1529 performs a self-test checking the system, all chan-
nels, calibration, GPIB, memory, and buttons. If an error occurs, an error message is
displayed. See Section 10.1, Troubleshooting on page 125 for additional information
on error messages.
5.7 Display Backlight and Contrast
The display backlight is adjustable for use in varying lighting conditions. The four
backlight modes are accessible in the CHANNEL menu DISPLAY OPTIONS func-
tion. If the display appears faded, dark, or blank, adjust the contrast (off, low, medium,
high) using the front panel contrast buttons.
5.8 Taking Measurements
The procedure for conguring the 1529 thermometer readout to take measurements
on a particular input channel requires the following: (1) connecting the sensor to the
appropriate input channel , (2) enabling the channel, and (3) selecting the conversion
type and probe characterization values.
5.8.1 Connecting the Sensor
Connect the sensor to the RTD/Thermistor channel(s) or thermocouple channel(s) that
you want to measure. Refer to Section 5.4, Probe Input Modules on page 18, for ad-
ditional information.
5.8.2 Enabling the Channel
Channels are set rst by selecting either simultaneous or scan mode in the CHANNEL
menu CHANNEL MODE function. Simultaneous mode shows one to four channels
in the upper display simultaneously. Scan mode shows one channel at a time (in large
digit format) scanning through one to four channels depending on the channels that
are enabled. After the mode has been selected, use the CHANNEL menu ENABLE
CHANNEL function, to select the channel to be displayed. Any channel set to ‘Off’ is
not displayed. See Section 6.1.3, Channel Mode on page 26, and Section 6.1.2, Enable
Channel on page 26, for more information.
5.8.3 Selecting Conversion Type and Probe Characterization
Before the 1529 can accurately measure temperature, it must be congured to calcu-
late temperature from the resistance or voltage of the sensor. There are many tempera-
ture conversion algorithms available and the one to use depends on the type of sensor
and its calibration. Many conversion algorithms use coefcients that characterize the
sensor. Coefcients are determined when the sensor is calibrated. SPRTs and RTDs
often use the ITS-90 algorithms and are provided with ITS-90 characterization coef-
cients. Thermistors often use the Steinhart-Hart algorithms and coefcients. Thermo-
couples use standard tables or equations depending on its type. For additional informa-
tion on conversion types, see Section 6.2, Probe Menu on page 29.
1529 Chub-E4 Thermometer Readout
Fast Measurement Mode
22
The conversion type and characterization coefcients for a sensor are specied using
the PROBE menu EDIT PROBE function (see Section 6.2.1, Edit Probe on page 30).
5.9 Fast Measurement Mode
Fast Measurement Mode applies to measure periods of 0.1, 0.2, or 0.5 seconds. This
mode allows measurements to be displayed or logged quickly.
Normally, when each measurement is made a self-calibration of the measurement cir-
cuit is performed simultaneously during the measurement process to offset errors from
component drift and spurious EMFs. For measure periods of 0.1, 0.2, and 0.5 seconds,
the fast measurement rate is achieved by foregoing the self-calibration. The drawback
to this Fast Measurement Mode is the accuracy of the measurement may be poor and
subject to drift. Accuracy can be temporarily improved using the AUTO-CAL func-
tion that appears in the CHANNEL menu when in this Fast Measurement Mode. The
AUTO-CAL function causes the instrument to perform a single self-calibration of the
measurement circuit then resume fast measuring (without automatic self-calibration).
See Section 6.1.1, Measure Period and Fast Measurement Mode on page 24 for de-
tailed information on using the Fast Measurement Mode.
5.10 Data Logging
Data can be logged either on demand or automatically at a user-selected interval.
When data is logged, readings are stored to the instrument’s memory and assigned a
label for easy recall and organization of data. Up to 100-demand log and 8,160 auto
log readings can be stored. When data is being logged, the left bottom corner of the
main display shows a strip-recorder indicator.

6.2.1.1 ITS-90 Conversion
The ITS-90 conversion is for PRTs calibrated and characterized using the Internation-
al Temperature Scale of 1990 equations. The parameters that appear when ITS-90 is
selected are RTPW, A4, B4, A, B, C, and D. These should be set with the correspond-
ing values that appear on the calibration certicate for the PRT. The parameter RTPW
takes the triple point of water resistance from the certicate. The parameters A, B, C,
and D take the an, bn, cn, and d coefcients from the certicate, where n is a number
from 6 to 11. Parameters A4 and B4 take the a4 and b4 coefcients on the certicate.
Any ITS-90 parameter of the 1529 that does not have a corresponding coefcient on
the PRT certicate must be set to 0.
When the ITS-90 conversion type is selected, the RANGE, WIRES, and coefcients
are displayed on the right portion of the bottom of the display. The UD buttons are
used to scroll through the coefcients. Use the Enter button to edit and to save the
new settings. Use the LR buttons to change each digit of the settings. Press and
hold the Exit button to cancel to the main display or press the EXIT button to cancel
and to move to the next parameter. On the last parameter, press the Exit button to exit
the menu.
The RANGE parameter is used to select the appropriate resistance range. For 25 ohm
and 100 ohm PRTs select 100 ohms and for 1000 ohm PRTs select 10K ohms.
The WIRES parameter sets the appropriate number of lead wires from the sensor.
This parameter can be set to 2-, 3-, or 4-wires. See Figure on page for the wiring
conguration.
The following table shows which parameter to set for each of the coefcients that may
appear on the certicate. Note: If the certicate has two sets of coefcients, one set for
“zero-power” calibration and one set for 1 mA calibration, use the coefcients for the
1 mA calibration.)

used, as is the case with some calibrations, A2 should be set to 0.0.
Note: Thermistor coefcients stated on the thermistor calibration report may be
labeled differently. The best way to identify the coefcients to use with this type
is to match the equation above with the equation given on the calibration report.
Also, recognize that the coefcients for this equation generally have negative

the YSI-400 series of thermistors.
There are no user programmable coefcients associated with this conversion type. Use
the Enter button or Exit button to exit the menu.
6.2.1.9 Thermocouple Volts [Vin[mV]]
The thermocouple volts displays the measurement in volts rather than temperature.
Note: When selecting volts as the conversion type for thermocouples, no cold-junction
compensation is available. The value measured and displayed is the uncompensated
voltage as sensed at the input of the module.
There are no user programmable coefcients associated with this conversion type. Use

6.2.1.10 Standard Thermocouple Conversions
Note: An Application Note for use of Tungsten-Rhenium and other thermocou-
ples is available at www.hartscientic.com.
Standard thermocouple conversions include types B, E, J, K, N, R, S, T, and Au-Pt.
Voltage is converted to temperature using standard reference functions. (For additional
information consult the publication NIST Monograph 175.)
You can specify internal or external reference junction compensation (RJC) with the
RJC parameter. (See Table on page .) With internal RJC, the temperature of the ther-
mocouple cold junction is measured automatically and used to calculate the absolute
temperature of the thermocouple. With external RJC, a reference junction at a known
xed temperature is used and the value of this xed temperature reference must be
entered in the RJT parameter and is used to calculate the absolute temperature of the
thermocouple.
Conversions for each of the thermocouple types accept functional calibration data.
This can be used to improve the measurement accuracy. The parameter, Tn, is the
temperature of the point in degrees Celsius. The parameter, ADJn, is the temperature
deviation from the reference function at the point in degrees Celsius. The temperature
measurement is adjusted by this amount when measuring at this temperature. A poly-
nomial interpolation function is used for measurements between calibration points. If
calibration data is not available or is not to be used, the ADJn parameters should all be
set to 0.0. This causes the temperature to be calculated according to the standard refer-
ence functions.

The user-dened parameters for the thermocouple polynomial conversion are the
coefcients c0 (C0) through c6 (C6). The user can specify internal or external refer-
ence junction compensation (RJC; see Table on page ). If external RJC is selected, the
user enters the temperature of the RJC reference in the reference junction temperature
(RJT) parameter.
The output of the thermocouple, in millivolts, at 25 °C with the reference junction at
0 °C, is mV (25 °C). For example, for a type K thermocouple, mV(25 °C) is 1.0002.
6.2.2 Copy Probe
The COPY PROBE function (Figure 15 on next page) allows you to copy a set of
probe parameters from one channel or memory location to another. The parameters
are copied from the user selected source channel or memory location into the current
channel. The COPY PROBE function can be password protected to restrict access. See
Section , Password, for more information. If this function is password protected, the
user is prompted to enter the password to gain access. If an incorrect password is en-
tered, the display shows the message PASSWORD INCORRECT and access is denied.
If the correct password is entered or if this function is not password protected, the

Auto log values are stored exactly as they appear on the upper portion of the display.
The resolution, units, and the channels displayed should be set up prior to auto logging
in order to ensure proper storage of data. All displayed channels are stored during
an auto log session. If the upper portion of the display is changed while data is being
auto logged, the data collected is modied from the time the display was changed. For
example, if a channel is disabled while auto logging, that channel stops being stored
from the time it was disabled.

1 hour. The LOG PER must be set to a value less than or equal to the measurement pe-
riod. The 1529 will not log readings faster than the measurement period. The measure-
ment period is set in the MEASURE PERIOD function of the CHANNEL menu and is
the rate at which readings are taken.
If the log period is set to a value less than the measure period the following message is
displayed in the lower portion of the display.

Digital Communications Interface
Communications
7 Digital Communications Interface
7.1 Overview
The communication feature allows an external device, such as a computer, to com-
municate with the 1529 to obtain measurement data and control operating conditions.
Communication is accomplished by issuing commands to the 1529 through RS-232 or
IEEE-488 communication ports.
7.2 Communications
The thermometer readout is equipped with an RS-232 serial interface, and optionally
a GPIB port. The serial interface allows communications up to distances of approxi-
mately 50 feet. The serial interface and GPIB port allow the user to access the func-
tions, parameters, and settings discussed in Section 6, Menu Functions on page 23.
7.2.1 Serial Wiring
The serial communications cable attaches to the thermometer readout through the
DB-9 connector at the back of the instrument. Figure 48 on next page shows the
pin-out of this connector and suggested cable wiring. This type of cable is typically
referred to as a “null modem” cable. To eliminate noise, the serial cable should be
shielded with low resistance between the connector (DB9) and the shield.
1529 Chub-E4 Thermometer Readout
Communications
68
Figure 48 Serial Cable Wiring
The serial period, baud rate, linefeed, and echo are programmable. Refer to Section ,
Serial Port, for instructions on accessing and setting these parameters.
All commands sent to the 1529 through the serial interface must be terminated with a
carriage return or linefeed character.
7.2.2 GPIB Communications
The GPIB interface allows the Model 1529 to be connected to an IEEE-488 bus along
with other instruments. A system controller can remotely control the operation of the
Model 1529 and read measurements.
7.2.2.1 Capability
The Model 1529 GPIB interface conforms to standard IEEE-488.2, 1992. Its capa-
bilities are identied as SH1, AH1, T6, L4, SR1, DC1, and E2. The interface has the
capabilities of talk, listen, serial poll, and device clear. There is no capability for talk-

Interface Commands
only, listen-only, extended talk or listen, parallel poll, remote-local control, or trigger
nor can it act as a controller. The IEEE-488 commands GET, GTL, LLO, and REN are
accepted without error but ignored.
7.2.2.2 Connection
The IEEE-488 port is located on the back of the 1529. Use a standard IEEE-488 cable
to connect to your GPIB controller. A shielded cable should be used to prevent EM
emission.
7.2.2.3 Device Setup
The Model 1529 system must be set up to respond to the controller address. Refer to
Section 6.5.1.2, GPIB (Optional) on page 61, for setting address and other parameters
for the IEEE-488 port.
7.3 Interface Commands
7.3.1 Command Summary
An alphabetical listing of the commands implemented by the 1529 are shown in Table
7 on this page. These commands can be used with either serial or IEEE-488 communi-
cations ports.

7.3.2 Command Syntax
The 1529 accepts commands that set parameters, execute functions or respond with
requested data. These commands are in the form of strings of ASCII-encoded charac-
ters. As far as possible, the 1529 conforms to IEEE-488.2, 1992 and SCPI-1994. One
notable exception is that compound commands are not allowed as explained below.
Commands consist of a command header and, if necessary, parameter data. All com-
mands must be terminated with either a carriage return (ASCII 0D hex or 13 decimal)
or new line character (ASCII 0A hex or 10 decimal).
Command headers consist of one or more mnemonics separated by colons (:). Mne-
monics may use letter characters, the underscore character (_), and possibly numeric
digits as well. Commands are not case sensitive. Mnemonics often have alternate
forms. Most mnemonics have a long form that is more readable and a short form con-
sisting of three or four characters that is more efcient.
A mnemonic may end with a numeric sufx that species one of a set of independent
function blocks such as input channel data paths. If a numeric sufx is omitted when a
particular block must be specied, an error is generated (“Header sufx out of range”).
Query commands are commands that request data in response. Query commands have
a question mark (?) immediately following the command header. Responses to query
commands are generated immediately and placed in the output buffer. Responses
are then transmitted automatically over the RS-232 port. When using the IEEE-488
interface, responses remain in the output buffer until read or until another command is
received or the power is turned off. Responses are lost if not read before the next com-
mand is received. Each input buffer holds 128 characters and each output buffer holds
256 characters.
Some commands require parameter data to specify values for one or more parameters.
The command header is separated from the parameter data by a space (ASCII 20 hex
or 32 decimal). Multiple parameters are separated by a comma (,).
The 1529 does not allow compound commands (multiple commands per line separated
with semicolons). All commands are sequential. The execution of each command is
completed before subsequent commands are processed.

7.4 Commands
Table 7 on page 69, Alphabetical List of Commands, lists the commands in alphabeti-
cal order. In this section the commands are arranged into the following groups:
Measurement Commands – commands for reading measurement data.
Measurement Control Commands – commands for the timing and action of the
measurement process.
Channel Commands – commands for selecting channels.
Probe Commands – commands for temperature conversion and probe
characterization.
Calibration Coefcient Commands – commands for channel calibration coefcients.
Display Commands – commands for display options and settings.
Logging Commands – commands for automatic and demand logging.
System Commands – commands for general system conguration parameters.
Communication Interface Commands – commands for controlling the interface
conguration(serial port and IEEE).
Date and Time Commands – commands for setting the date, time and the date and
time formats.
Password Commands – commands for enabling and disabling the password, for set-
ting the password, and for checking the state of the password.
Status Commands – commands to report the status and condition of the instrument.
Each section provides the command structure (long and short format), a description of
the command purpose, a command example, an example of what the command returns
(as applicable to query commands), and notes specic to the command. The following
apply to each group of commands.
● Numeric data, specied by the mnemonic, <num>, uses ASCII characters to
represent numbers. Numbers may contain a plus or minus (‘+’ or ‘-’) sign,
decimal point (‘.’), and exponent (‘E’ or ‘e’) with its sign. If a fractional
component is received when only an integer is required, the number is rounded
to the nearest integer without any resulting error message. The mnemonics DEF,
MIN, and MAX are often acceptable for the default, minimum, and maximum
value respectively. Unit sufxes, such as V or OHM, can be appended to
numeric parameters and are accepted without error but ignored.
● Unrecognized commands or commands with incorrect syntax or invalid
parameters generate error messages in the error queue.
● Upper case letters designate syntax that is required when issuing the command.
Lower case letters are optional and may be omitted.
● <> indicates a required parameter.
● [] indicates optional parameters.
● () indicates a group of parameters that must be used together.

Calibration
PRT and Thermistor Calibration
8 Calibration
Each channel of the 1529 is calibrated independently of the other channels and has its
own set of calibration parameters. The 1529 should be calibrated at regular intervals
to ensure that it continues to measure with proper accuracy. Calibration should only be
done by qualied, authorized personnel. When the 1529 is recalibrated, all four chan-
nels are calibrated each calibration cycle. The calibration label indicates the calibration
date and recalibration due date for the entire instrument.
8.1 PRT and Thermistor Calibration
The following information is for PRT and thermistor channel calibrations. The adjust-
able parameters are listed in the following table.

Parameter Description
C0 PRT offset parameter
C100 PRT scale parameter
C400 PRT linearity parameter
C0K Thermistor offset parameter
C10K Thermistor scale parameter
C100K Thermistor linearity parameter
DATE Records the date the PRT or Thermistor channel was calibrated
DUE Record the date the PRT or Thermistor channel calibration expires
8.1.1 PRT Calibration Parameters
Three adjustable parameters are used for calibration: C0, C100, and C400. The C0
parameter directly affects the measurement at 0 W. It has negligible effect at 100 W but
signicant affect at higher resistances. The C100 parameter directly affects the mea-
surement at 100 W. It has negligible effect at 0 W and proportionately greater effect the
higher the resistance. The C400 parameter directly affects the measurement at 400. It
has negligible effect at 0 W and 100 W with greater effect as the resistance increases.
Each of the parameters has positive effect at their primary resistances: increasing the
value of the parameter increases the measured resistance. The theoretically normal
value for each is 0.
The calibration parameters C0, C100, and C400 can be adjusted to optimize the ac-
curacy. These password-protected parameters are accessed from the CALIBRATION
function of the SYSTEM menu.
8.1.2 PRT Calibration Procedure
Calibration requires adjustment of the C0, C100, and C400 parameters at three specic
input resistances. If the resistances used are approximately 0 W, 100 W and 400 W
respectively the adjustments are independent and the procedure is simple. The order
in which the adjustments are performed is important. The adjustment of the C400 pa-
1529 Chub-E4 Thermometer Readout
PRT and Thermistor Calibration
118
rameter must be done last as the adjustments of C0 and C100 affect the measurement
at 400 W but C400 does not affect the measurements at 0 W or 100 W. Each channel
must be calibrated. Set the conversion type to RES to display resistance (see Sec-
tion 6.2.1.5, RES Conversion on page 34) and the RANGE parameter to 100 W. The
calibration should be performed with a four-wire connection and with the probe wiring
parameter set to four-wire (see Section 5.4, Probe Input Modules on page 18). The
accuracy required of the resistance standards is 1/4 of the instrument accuracy; that is
±0.000125 W at 0 W, ±0.0006 W ( 6 ppm) at 100 W, and ±0.0024 W (6 ppm) at 400 W.
The recommended procedure is as follows:
1. Connect a 0W resistor to the input and measure its resistance. If a shorting
wire is used the wire should run from the C2 terminal to the C1 terminal to
the P1 terminal to the P2 terminal (See Figure ). Note the average error in the
measurement. Adjust the C0 parameter by subtracting the measured error. For
example, if the input is exactly 0.0000 and the readout shows –0.0011, adjust
the C0 parameter by adding 0.0011.

Using a Shorting Wire
2. Connect a 100 W resistor (6 ppm accuracy) to the input and measure its
resistance. Note the average error in the measurement. Adjust the C100
parameter by subtracting the measured error. For example, if the input is exactly
100.0000 W and the readout shows 100.0295 W, adjust the C100 parameter by
subtracting 0.0295.
3. Connect a 400 W resistor (6 ppm accuracy) to the input and measure its
resistance. Note the average error in the measurement. Adjust the C400
parameter by subtracting the measured error. For example, if the input is exactly
400.0000 W and the readout shows 399.9913 W, adjust the C400 parameter by
adding 0.0087.
4. Record the date in the DATE parameter and set the DUE parameter to the
desired calibration interval.
5. Verify the accuracy at 0 W, 25 W or 50 W, 100 W, 200 W, and 400 W on each
channel.

Calibration
PRT and Thermistor Calibration
8.1.3 Thermistor Calibration Parameters
Three adjustable parameters are used for calibration: C0K, C10K, and C100K. The
C0K directly affects the measurement at 0 W. It has negligible effect at 10 kW but
signicant affect at higher resistances. The C10K directly affects the measurement at
10 kW. It has negligible effect at 0 W and proportionately greater effect the higher the
resistance. The C100K directly affects the measurement at 100 kW. It has negligible
effect at 0 W and 10 kW with greater effect as the resistance increases. Each of the
parameters has positive effect at their primary resistances: increasing the value of the
parameter increases the measured resistance. The theoretically normal value for each
is 0.
The calibration parameters C0K, C10K, and C100K can be adjusted to optimize the
accuracy. These parameters are accessed from the CALIBRATION function of SYS-
TEM menu.
8.1.4 Thermistor Calibration Procedure
Calibration requires adjustment of the C0K, C10K, and C100K parameters at three
specic input resistances. If the resistances used are approximately 0 W, 10 kW and
100 kW respectively the adjustments are independent and the procedure is simple.
The order in which the adjustments are performed is important. The adjustment of the
C100K parameter must be done last as the adjustments of C0K and C10K affect the
measurement at 100 kW but C100K does not affect the measurements at 0 W or 10 kW.
Each channel must be calibrated. Set the conversion type to RES to display resistance
and set the RANGE parameter to 10KW. The accuracy required of the resistance stan-
dards is 1/4 of the instrument accuracy; that is 0.12W at 0 W, 0.25 W (25 ppm) at 10
kW, and 2.5 W (25 ppm) at 100 kW. The recommended procedure is as follows:
1. Connect a 0W resistor to the input and measure its resistance. If a shorting wire
is used the wire should run from the C2 terminal to the C1 terminal to the P1
terminal to the P2 terminal (See Figure on page ). Note the average error in the
measurement. Adjust the C0K parameter by subtracting the measured error. For
example, if the input is exactly 0.0 W and the readout shows –0.11 W, adjust the
C0K parameter by adding 0.11.
2. Connect a 10 kW resistor (25 ppm accuracy) to the input and measure its
resistance. Note the average error in the measurement. Adjust the C10K
parameter by subtracting the measured error. For example, if the input is exactly
10.00000 kW and the readout shows 10.00295 kW, adjust the C10K parameter
by subtracting 2.95.
3. Connect a 100 kW resistor (25 ppm accuracy) to the input and measure its
resistance. Note the average error in the measurement. Adjust the C100K
parameter by subtracting the measured error. For example, if the input is exactly
100.0000 kW and the readout shows 99.9913 kW, adjust the C100K parameter
by adding 8.7.
4. Record the date in the DATE parameter and set the DUE parameter to the
desired calibration interval.
5. Verify the accuracy at 0 W, 4k W, 10 kW, 40 kW, 100 kW, and 500 kW on each
channel.

8.2 Thermocouple Calibration
The following information is for a Thermocouple calibration. See Section 8.1, PRT
and Thermistor Calibration on page 117 for PRT and thermistor calibrations.
8.2.1 Calibration Parameters
Three adjustable parameters are used for calibration of each thermocouple channel.
They are listed in Table 18, Calibration Parameters.
Table 18 Calibration Parameters
Parameter Description
C0 Adjusts the voltage accuracy of at 0 mV
C100 Adjusts the voltage accuracy of at 100 mV
CRJ Adjusts the internal RJC accuracy
DATE Records the date the thermocouple channel was calibrated
DUE Records the date the thermocouple channel calibration expires
The calibration parameters can be accessed from the CALIBRATION function of
SYSTEM menu
8.2.2 Calibration Procedure
Calibration of each channel is performed in two steps. First the voltage measurement
is calibrated then the internal RJC is calibrated. The equipment required are a pro-
grammable voltage source, a precision voltmeter with an accuracy of 10 ppm or better,
a thermocouple (preferably type E), and a temperature source between 0 and 30 °C.
The combined accuracy of the reference thermocouple and temperature source must be
0.06 °C or better between the reference temperature and ambient temperature. At each
step during the calibration procedure the readings should be allowed to settle for at
least two minutes before recording the measurement. Also, the 1529 should be allowed
to warm up for at least one hour after power up prior to calibration. The recommended
procedure is as follows:
1. Connect the voltage source to the thermocouple channel, set it for 0 mV, and
measure the voltage with the 1529 and the voltmeter simultaneously. Adjust
the C0 parameter by subtracting the measured error. For example, if the 1529
measures –0.0006 mV, adjust the C0 parameter by adding 0.0006. If it was
previously 0.0000 it should now be 0.0006.
2. Set the voltage source to 100 mV and measure the voltage with the 1529 and
the voltmeter simultaneously. Adjust the C100 parameter by subtracting the
measured error. For example, if the input is exactly 100.0000 mV and the 1529
shows 100.2953 mV, the C100 parameter should be adjusted by subtracting
0.2953. If it was previously 0.0000 it should now be –0.2953.
3. Verify the voltage accuracy at 0, 50, and 100 mV. The accuracy must be within
the short-term voltage accuracy given in the specications.
121
Calibration
Thermocouple Calibration
4. Connect the calibrated thermocouple to the thermocouple channel and insert
the thermocouple into the temperature source. Measure the temperature with
the 1529 (be sure to program the channel with the correct thermocouple type).
Adjust the CRJ parameter by subtracting the measured error. For example, if
the thermocouple temperature is actually 0.0 °C but the 1529 reads 0.184 °C,
the CRJ parameter should be adjusted by subtracting 0.184. If it was previously
0.000 it should now be –0.184.
5. Record the date with the DATE parameter. Set the DUE date to the desired
calibration interval.
6. Repeat the procedure for any other thermocouple channels.
123
Maintenance
9 Maintenance
● The calibration instrument has been designed with the utmost care. Ease of
operation and simplicity of maintenance have been a central theme in the
product development. Therefore, with proper care the instrument should require
very little maintenance. Avoid operating the instrument in oily, wet, dirty, or
dusty environments.
● If the outside of the instrument becomes soiled, it may be wiped clean with
a damp cloth and mild detergent. Do not use harsh chemicals on the surface,
which may damage the LCD or the plastic front panel.
● If a hazardous material is spilt on or inside the equipment, the user is
responsible for taking the appropriate decontamination steps as outlined by the
national safety council with respect to the material.
● Before using any cleaning or decontamination method except those
recommended by Hart, users should check with an Authorized Service Center
(see Section 1.3, Authorized Service Centers on page 4) to be sure that the
proposed method will not damage the equipment.
● If the AC adapter becomes damaged, have it replaced immediately. Never
disassemble the AC adapter or attempt to repair it.
● If the instrument is used in a manner not in accordance with the equipment
design, the operation of the thermometer readout may be impaired or safety
hazards may arise.
● Periodic calibration of the instrument at regular intervals is required to ensure
that it continues to measure with proper accuracy. Calibration should only be
performed by qualied authorized personnel.

Troubleshooting
Troubleshooting
10 Troubleshooting
In case you run into difculty while operating the 1529 system, this section provides
some suggestions that may help you solve the problem. Below are several situations
that may arise followed by possible causes and suggested actions you might take.
10.1 Troubleshooting
The following table lists possible error messages, their causes, and suggested actions.
Problem Solution
Incorrect temperature reading While attempting to measure temperature, the display shows an incorrect value or no value at all
( . . . . . . . . . ).
● If the temperature readings seem to be incorrect you should first check to see if the
resistance, or voltage in the case of thermocouples, is being measured correctly. Set up the
display to show the resistance or voltage for the channel.
● If the resistance or voltage is incorrect refer to the next subsection for troubleshooting
incorrect resistance or voltage readings.
● If the resistance or voltage is being measured correctly but the displayed temperature value
is incorrect consider the following possibilities:
One or more coefficients are incorrect. This is a common mistake. While entering coefficients
it is easy to miss a digit or sign. Check all the values carefully using the EDIT PROBE function
(see Section 6.2.1, Edit Probe on page 30) comparing them with the values on the calibration
certificate for the probe. Use the TEST PROBE function to test the coefficients (see Section
6.2.1.10, Standard Thermocouple Conversions on page 36).
The selected conversion type is incorrect. Check to make sure the correct conversion
type is selected. In the case of thermocouples, make sure you have selected the
correct type. You should also make sure that you have selected the proper reference
junction compensation (RJC) made for your application see Section 6.2.1.10, Standard
Thermocouple Conversions on page 36). You can use the TEST PROBE function to test the
temperature conversion calculation.
The measurement is out of range. The 1529 may not be able to calculate temperature
accurately if the resistance or voltage is outside the valid range. The measured resistance
or voltage may be too low or too high if the actual temperature is too low or too high or if
there is a problem with the sensor.
● The measure period may be set to a long interval. Check the measure period setting.

Problem Solution
Incorrect resistance or voltage
reading
While attempting to measure resistance or voltage, the display shows an incorrect value or no
value at all
(. . . . . . . . . . ).
Consider the following possibilities:
Poor or incorrect connection of the probe. A common mistake is to connect the wires of the
probe to the wrong terminals. Check the wiring carefully, especially when using a four-wire PRT
(see Section ). Make sure the lead wires are fastened down tightly.
Open, shorted, or damaged sensor or lead wires. In the case of resistance sensors check
the resistance across the sensor using a hand-held DMM. Also check the resistance between
common pairs of leads. Check to make sure there is no conductivity between any of the leads
and the probe sheath. Use a good-quality sensor to avoid errors caused by drift, hysteresis, or
insulation leakage. In the case of thermocouples, use a hand-held DMM to check its voltage.
Improper setting for three or four-wire probe. Make sure the correct wiring type is selected
Selecting three-wire input while using four-wire probes may cause errors of 0.01 to 0.1 ohms.
Selecting four-wire input while using three-wire probes will result in erratic or out-of-range
readings (see Section 5.4.1, Connecting a PRT or Thermistor Probe on page 18).
Electrical interference. Intense radio-frequency radiation near the 1529 or probes can induce
noise into the measurement circuits resulting in erratic readings. The 1529 is intended to operate
in a laboratory environment with limited radio-frequency noise. If interference seems to be a
problem you might try eliminating the source of interference or moving the 1529 to a different
location. A well-grounded, shielded cable should be used for the probe leads.
Stem conduction error. The problem may be that the actual temperature of the sensor is not
what you expect. This is often the result of stem conduction where heat flowing through the stem
of the probe to ambient affects the temperature of the probe. It is very important that probes be
inserted to an adequate depth into the material being measured. Measuring temperature using a
surface sensor can be especially difficult as the sensor is directly exposed to ambient.
Wrong calibration parameters. The problem may be that the calibration parameters for the 1529
are invalid. Check the parameters currently stored in the unit against those listed on the 1529
Report of Calibration.
Blank screen The screen lights up when the 1529 is switched on but the screen appears blank. This
problem can be caused by improper adjustment of the contrast. After the power is switched on
allow the 1529 at least one minute to complete its self-test and power on sequence. Then, try to
adjust the contrast using the contrast buttons.
Error message at power up The 1529 reports an error during the power up self-test. On power up the 1529 performs a
series of self-tests to check the operation of all its components and each of the modules. The
results of the self-tests are reported on the screen. Normally, all tests report ‘OK’. Below is a
table of error messages and recommended actions to correct the error. Often these errors can
be corrected by completing the actions listed. A failure of one or more component causes error
messages to be reported. Component failures generally require a qualified factory technician to
replace the faulty component. Contact an Authorized Service Center (see Section 1.3, Authorized
Service Centers on page 4).

10.4 Frequently Asked Questions
10.4.1 Battery
1. What type of batteries does the Model 1529 use? The Model 1529 uses a built-
in Nickel-Metal-Hydride battery pack.
2. How long do I need to charge the battery initially? The batteries come fully
charged. If for some reason they are not fully charged, the front panel indicator
shows this and you can recharge them as needed.
3. How long does the battery take to fully charge? About 3 hours from fully
discharged.
4. How long does the battery last from full charge? About 8 hours from full
charge with the backlight off.
5. How do I know when the battery is at full charge? The charging indicator LED
located on the back panel displays amber while charging and then turns green
when the batteries are fully charged (only when the AC adapter is connected).
The front panel indicator at the bottom right shows when the batteries are in use
and their approximate charge state.
6. How does the backlight affect the battery life? With the backlight on low the
battery life is reduced by 25%, medium by 30%, and high by 40%.
7. Do I have to let the battery fully discharge before charging? No, the batteries
do not need to be fully discharged before recharging. You may recharge them at
any time.
8. Is it recommended that I allow the battery pack to fully discharge occasionally?
In order to maintain the charge/discharge characteristics of the battery, Hart
recommends that you allow the battery to discharge completely once a month.
You do this by allowing the Model 1529 to operate on battery power until it
shuts down on its own.
9. If I allow the battery pack to fully discharge, what happens to the calibration
parameters stored in the Model 1529? Parameters used by the Model 1529 are
stored in non-volatile RAM (NVRAM). This IC stores the parameters even
when power is not applied.
10. How many recharge cycles is the battery good for? Approximately 500.
1529 Chub-E4 Thermometer Readout
Frequently Asked Questions
130
11. What happens to my measurement accuracy when the battery is low? The
Model 1529 does not display temperature when there is not sufcient power to
make a correct measurement.
12. If I am using the autolog and the battery runs out will I lose my data? No, you
won’t lose any data. The Model 1529 simply stops logging data. When the AC
adapter is plugged in, the data logging continues.
13. How do I dispose of the batteries used in the Model 1529? Disposal guidelines
can be found by consulting your local governing authority.
14. If the AC adapter is plugged in and I have the unit turned on, is the battery
still charging? Yes, the Model 1529 charges while in use without affecting the
charging time or its performance.
15. If I am using the Model 1529 with AC power and a power outage occurs, will
the batteries automatically take over? Yes, when AC power is removed from
the Model 1529 for any reason, the batteries automatically supply back up
power without risk of losing any data.
10.4.2 Input
1. Can I swap out measurement boards in the eld? No, the measurement boards
were not designed to be exchanged in the eld.
2. What are the implications of the fast measurement mode in terms of accuracy?
Accuracy is reduced when using the Model 1529 in fast measurement mode.
Refer to Section 6.1.1, Measure Period and Fast Measurement Mode on page 24
for a better description of the fast measurement mode and its limitations.
3. Why can I only see one channel in the fast measurement mode? Because of
the time required to make a measurement and update the display, there is not
enough time to display more than one channel when in the fast measurement
mode.
4. Do I have to reprogram the Model 1529 each time I swap out a probe? In
addition to the four main channels, there are nine memory locations available to
store probe coefcients. If the new probe’s information has been programmed
into one of these locations, you can copy it to the channel to which it is
connected.
5. How does the moving average affect the data that is logged? The data collected
by the Model 1529 is stored as it appears on the display. If you set the Model
1529 to average the measurements, the data it logs reects the moving average
setting.
6. How many probe coefcients can I store? Thirteen. Four sets in the main
channels and nine sets in memory locations.
7. Are the readings really simultaneous in the simultaneous mode? Yes. There
are four measurement circuits that collect the raw data simultaneously. The raw
data is then converted to its corresponding temperature in sequence taking less
than 0.5 seconds for all four channels.
8. How does the three-wire RTD setting affect my overall accuracy? When using
the three-wire setting in the Model 1529, a partial compensation of lead-wire
resistance is performed as per normal industry practices. Since a three-wire
131
Troubleshooting
Frequently Asked Questions
measurement can’t fully compensate for lead resistaance, accuracy is reduced.
As stated in the specication section of this manual, you need to add 0.05W to
the measurement accuracy plus the maximum possible difference between the
resistances of the lead wires.
10.4.3 Logging
1. How many data points can the Model 1529 store? You can store up to 100
demand log readings and 8,000 autolog readings.
2. What happens when the log memory is full? Logging stops once the memory is
full. Readings are not deleted to make room for new readings.
3. How can I tell when the log memory is full? Full memory is indicated in the
log stats function in the logging menu. You can also program a eld in the
lower display to show the autolog memory status.
4. Can I use the Model 1529 for other applications while I am autologging? Yes,
the Model 1529 can be used while logging. However, keep in mind that the
channels that are displayed are also logged. Changing the channels affects the
data that is logged.
10.4.4 Output
1. How do I get data from the Model 1529 to my PC? Data can be transferred to
your PC via an RS-232 interface.
2. Can the Model 1529 be set to simultaneous measurement mode and log to the
serial port? Yes. The Model 1529 makes the measurements simultaneously and
transmits them to the serial port. However, most printers can’t print as fast as
the data is logged so it doesn’t appear to be simultaneous.
10.4.5 Other
1. Can I update the Model 1529 rmware without sending in my unit? Yes.
Firmware updates include a utility program that installs the upgrade via the RS-
232 port.
2. How do I change the password? Changing the password is explained in Section
6.5.3, Password on page 62.
3. How often does the Model 1529 need to be recalibrated? We suggest that
the unit be calibrated annually, but that may vary based upon usage and your
company’s policies.
