Power-Up Options
Holding a button down while turning the Meter on activates
a power-up option. Table 4 includes the power-up options.
Automatic Power-Off
The Meter automatically turns off if you do not turn the
rotary switch or press a button for 30 minutes. If MIN MAX
Recording is enabled, the Meter will not power off. To
disable automatic power-off, refer to Table 4.
Input Alert
Feature
If a test lead is plugged into the mA/µA or A terminal, but
the rotary switch is not set to the correct current position,
the beeper warns you by making a chirping sound and the
display flashes “LEAd”. This warning is intended to stop
you from attempting to measure voltage, continuity,
resistance, capacitance, or diode values when the leads
are plugged into a current terminal.
W Caution
Placing the probes across (in parallel with) a
powered circuit when a lead is plugged into a
current terminal can damage the circuit you
are testing and blow the Meter's fuse. This
can happen because the resistance through
the Meter's current terminals is very low, so
the Meter acts like a short circuit.
Making Measurements
The following sections describe how to take
measurements with the Meter.
Measuring AC and DC Voltage
Model 87 features true rms readings, which are accurate
for distorted sine waves and other waveforms (with no dc
offset) such as square waves, triangle waves, and
staircase waves.
The Meter's voltage ranges are 600.0 mV, 6.000 V,
60.00 V, 600.0 V, and 1000 V. To select the 600.0 mV dc
range, turn the rotary switch to mV.
To measure ac or dc voltage, refer to Figure 2.
80 Series V
Users Manual
14
When measuring voltage, the Meter acts approximately
like a 10 MΩ (10,000,000 Ω) impedance in parallel with
the circuit. This loading effect can cause measurement
errors in high-impedance circuits. In most cases, the error
is negligible (0.1% or less) if the circuit impedance is
10 kΩ (10,000 Ω) or less.
For better accuracy when measuring the dc offset of an ac
voltage, measure the ac voltage first. Note the ac voltage
range, then manually select a dc voltage range equal to or
higher than the ac range. This procedure improves the
accuracy of the dc measurement by ensuring that the
input protection circuits are not activated.

Zero Input Behavior of True RMS Meters (87)
True Rms Meters accurately measure distorted
waveforms, but when the input leads are shorted together
in the AC functions, the meter displays a residual reading
between 1 and 30 counts. When the test leads are open,
the display readings may fluctuate due to interference.
These offset readings are normal. They do not affect the
Meter’s AC measurement accuracy over the specified
measurement ranges.
Unspecified input levels are:
• AC voltage: below 3 % of 600 mV AC, or 18 mV AC
• AC current: below 3 % of 60 mA AC, or 1.8 mA AC
• AC current: below 3 % of 600 µA AC, or 18 µA AC
Low Pass Filter (87)
The 87 is equipped with an ac low pass filter. When
measuring ac voltage or ac frequency, press A to
activate the low pass filter mode (K). The Meter continues
measuring in the chosen ac mode, but now the signal
diverts through a filter that blocks unwanted voltages above
1 kHz, refer to Figure 3. The lower frequency voltages pass
with reduced accuracy to the measurement below 1 kHz.
The low pass filter can improve measurement performance
on composite sine waves that are typically generated by
inverters and variable frequency motor drives.
XWWarning
To avoid possible electric shock or personal
injury, do not use the Low Pass Filter option
to verify the presence of hazardous voltages.
Voltages greater than what is indicated may
be present. First, make a voltage measure-
ment without the filter to detect the possible
presence of hazardous voltage. Then, select
the filter function.
Note
In Low Pass Mode, the Meter goes to manual
mode. Select ranges by pressing the RANGE
button. Autoranging is not available in Low Pass
Mode.

Measuring Temperature (87)
The Meter measures the temperature of a type-K
thermocouple (included). Choose between degrees
Celsius (°C) or degrees Fahrenheit (°F) by pushing C.
W Caution
To avoid possible damage to the Meter or
other equipment, remember that while the
Meter is rated for –200.0 °C to +1090.0 °C and
–328.0 °F to 1994.0 °F, the included K-Type
Thermocouple is rated to 260 °C. For
temperatures out of that range, use a higher
rated thermocouple.
Display ranges are –200.0 °C to +1090.0 °C and
–328.0 °F to 1994.0 °F. Readings outside of these ranges
show OL on the Meter display. When there is no
thermocouple connected, the display also reads OL.
To measure temperature, do the following:
1. Connect a type-K thermocouple to the Meter’s COM
and dV eG terminals.
2. Turn the rotary switch to M.
3. Press A to enter temperature mode.
4. Push C to choose Celsius or Fahrenheit.
Testing for Continuity
WCaution
To avoid possible damage to the Meter or to
the equipment under test, disconnect circuit
power and discharge all high-voltage
capacitors before testing for continuity.
The continuity test features a beeper that sounds as long
as a circuit is complete. The beeper allows you to perform
quick continuity tests without having to watch the display.
To test for continuity, set up the Meter as shown in
Figure 4.
Press Eto turn the continuity beeper on or off.
The continuity function detects intermittent opens and
shorts lasting as little as 1ms. A brief short causes the
Meter to emit a short beep.

Measuring Resistance
WCaution
To avoid possible damage to the Meter or to
the equipment under test, disconnect circuit
power and discharge all high-voltage
capacitors before measuring resistance.
The Meter measures resistance by sending a small
current through the circuit. Because this current flows
through all possible paths between the probes, the
resistance reading represents the total resistance of all
paths between the probes.
The Meter's resistance ranges are 600.0 Ω, 6.000 kΩ,
60.00 kΩ, 600.0 kΩ, 6.000 MΩ, and 50.00MΩ.
To measure resistance, set up the Meter as shown in
Figure 5.
The following are some tips for measuring resistance:
• The measured value of a resistor in a circuit is often
different from the resistor's rated value.
• The test leads can add 0.1 Ω to 0.2 Ω of error to
resistance measurements. To test the leads, touch
the probe tips together and read the resistance of the
leads. If necessary, you can use the relative (REL)
mode to automatically subtract this value.
• The resistance function can produce enough voltage
to forward-bias silicon diode or transistor junctions,
causing them to conduct. If this is suspected, press
C to apply a lower current in the next higher
range. If the value is higher, use the higher value.

Using Conductance for High Resistance or
Leakage Tests
Conductance, the inverse of resistance, is the ability of a
circuit to pass current. High values of conductance
correspond to low values of resistance.
The Meter's 60 nS range measures conductance in
nanosiemens (1 nS = 0.000000001 Siemens). Because
such small amounts of conductance correspond to
extremely high resistance, the nS range lets you
determine the resistance of components up to 100,000
MΩ, 1/1 nS = 1,000 MΩ.
To measure conductance, set up the Meter as shown for
measuring resistance (Figure 5); then press Cuntil
the nS indicator appears on the display.
The following are some tips for measuring conductance:
• High-resistance readings are susceptible to
electrical noise. To smooth out most noisy readings,
enter the MIN MAX recording mode; then step to the
average (AVG) reading.
• There is normally a residual conductance reading
with the test leads open. To ensure accurate
readings, use the relative (REL) mode to subtract
the residual value.

Measuring Capacitance
WCaution
To avoid possible damage to the Meter or to
the equipment under test, disconnect circuit
power and discharge all high-voltage
capacitors before measuring capacitance.
Use the dc voltage function to confirm that
the capacitor is discharged.
The Meter's capacitance ranges are 10.00 nF, 100.0 nF,
1.000 µF, 10.00 µF, 100.0 µF, and 9999 µF.
To measure capacitance, set up the Meter as shown in
Figure 6.
To improve the accuracy of measurements less than
1000 nF, use the relative (REL) mode to subtract the
residual capacitance of the Meter and leads.
Note
If too much electrical charge is present on the
capacitor being tested, the display shows
“
diSC
“.

Testing Diodes
WCaution
To avoid possible damage to the Meter or to
the equipment under test, disconnect circuit
power and discharge all high-voltage
capacitors before testing diodes.
Use the diode test to check diodes, transistors, silicon
controlled rectifiers (SCRs), and other semiconductor
devices. This function tests a semiconductor junction by
sending a current through the junction, then measuring
the junction's voltage drop. A good silicon junction drops
between 0.5 V and 0.8 V.
To test a diode out of a circuit, set up the Meter as shown
in Figure 7. For forward-bias readings on any
semiconductor component, place the red test lead on the
component's positive terminal and place the black lead on
the component's negative terminal.
In a circuit, a good diode should still produce a forward-
bias reading of 0.5 V to 0.8 V; however, the reverse-bias
reading can vary depending on the resistance of other
pathways between the probe tips.
A short beep sounds if the diode is good (< .85 V). A
continuous beep sounds if the reading is ≤ .100 V. This
reading would indicate a short circuit. The display shows
“OL” if the diode is open.

Measuring AC or DC Current
XWWarning
To avoid possible electric shock or personal
injury, never attempt an in-circuit current
measurement where the open-circuit
potential to earth is greater than 1000 V. You
may damage the Meter or be injured if the
fuse blows during such a measurement.
WCaution
To avoid possible damage to the Meter or to
the equipment under test:
• Check the Meter's fuses before
measuring current.
• Use the proper terminals, function, and
range for all measurements.
• Never place the probes across (in
parallel with) any circuit or component
when the leads are plugged into the
current terminals.
To measure current, you must break the circuit under
test, then place the Meter in series with the circuit.
The Meter's current ranges are 600.0 µA, 6000 µA,
60.00 mA, 400.0 mA, 6000 mA, and 10 A. AC current is
displayed as an rms value.
To measure current, refer to Figure 8 and proceed as
follows:
1. Turn off power to the circuit. Discharge all high-
voltage capacitors.
2. Insert the black lead into the COM terminal. For
currents between 6 mA and 400 mA, insert the red
lead into the mA/µA terminal. For currents above
400 mA, insert the red lead into the A terminal.
Note
To avoid blowing the Meter's 400 mA fuse, use
the mA/
µ
A terminal only if you are sure the
current is less than 400 mA continuously or less
than 600 mA for 18 hours or less.

3. If you are using the A terminal, set the rotary switch to
mA/A. If you are using the mA/µA terminal, set the
rotary switch to µA for currents below 6000 µA
(6 mA), or mA/A for currents above 6000 µA.
4. To measure dc current, press A.
5. Break the circuit path to be tested. Touch the black
probe to the more negative side of the break; touch
the red probe to the more positive side of the break.
Reversing the leads will produce a negative reading,
but will not damage the Meter.
6. Turn on power to the circuit; then read the display. Be
sure to note the unit given at the right side of the
display (µA, mA, or A).
7. Turn off power to the circuit and discharge all high-
voltage capacitors. Remove the Meter and restore the
circuit to normal operation.
The following are some tips for measuring current:
• If the current reading is 0 and you are sure the Meter
is set up correctly, test the Meter's fuses as described
under "Testing the Fuses".
• A current Meter drops a small voltage across itself,
which might affect circuit operation. You can calculate
this burden voltage using the values listed in the
specifications in Table 14.
Making Measurements
27
Measuring Frequency
The Meter measures the frequency of a voltage or current
signal by counting the number of times the signal crosses
a threshold level each second.
Table 6 summarizes the trigger levels and applications for
measuring frequency using the various ranges of the
Meter's voltage and current functions.
To measure frequency, connect the Meter to the signal
source; then press G. Pressing Eswitches the
trigger slope between + and -, as indicated by the symbol
at the left side of the display (refer to Figure 9 under
"Measuring Duty Cycle"). Pressing Dstops and starts
the counter.
The Meter autoranges to one of five frequency ranges:
199.99 Hz, 1999.9 Hz, 19.999 kHz, 199.99 kHz, and
greater than 200 kHz. For frequencies below 10 Hz, the
display is updated at the frequency of the input.
Below 0.5 Hz, the display may be unstable.
The following are some tips for measuring frequency:
• If a reading shows as 0 Hz or is unstable, the input
signal may be below or near the trigger level. You can
usually correct these problems by selecting a lower
range, which increases the sensitivity of the Meter. In
the L function, the lower ranges also have lower
trigger levels.
• If a reading seems to be a multiple of what you
expect, the input signal may be distorted. Distortion
can cause multiple triggerings of the frequency
counter. Selecting a higher voltage range might solve
this problem by decreasing the sensitivity of the
Meter. You can also try selecting a dc range, which
raises the trigger level. In general, the lowest
frequency displayed is the correct one.

Measuring Duty Cycle
Duty cycle (or duty factor) is the percentage of time a
signal is above or below a trigger level during one cycle
(Figure 9). The duty cycle mode is optimized for
measuring the on or off time of logic and switching
signals. Systems such as electronic fuel injection systems
and switching power supplies are controlled by pulses of
varying width, which can be checked by measuring duty
cycle.
To measure duty cycle, set up the Meter to measure
frequency; then press Hz a second time. As with the
frequency function, you can change the slope for the
Meter's counter by pressing E.
For 5 V logic signals, use the 6 V dc range. For 12 V
switching signals in automobiles, use the 60 V dc range.
For sine waves, use the lowest range that does not result
in multiple triggering. (Normally, a distortion-free signal
can be up to ten times the amplitude of the selected
voltage range.)
If a duty cycle reading is unstable, press MIN MAX; then
scroll to the AVG (average) display.

Determining Pulse Width
For a periodic waveform (its pattern repeats at equal time
intervals), you can determine the amount of time that the
signal is high or low as follows:
1. Measure the signal's frequency.
2. Press Ga second time to measure the signal's
duty cycle. Press E to select a measurement of
the signal's positive or negative pulse, refer to Figure
9.
3. Use the following formula to determine the pulse
width:
Pulse Width = % Duty Cycle ÷ 100
(in seconds) Frequency
Bar Graph
The analog bar graph functions like the needle on an
analog meter, but without the overshoot. The bar graph
updates 40 times per second. Because the graph
responds 10 times faster than the digital display, it is
useful for making peak and null adjustments and
observing rapidly changing inputs. The graph is not
shown for capacitance, frequency counter functions,
temperature, or peak min max.
The number of lit segments indicates the measured value
and is relative to the full-scale value of the selected
range.
In the 60 V range, for example, the major divisions on the
scale represent 0, 15, 30, 45, and 60 V. An input of -30 V
lights the negative sign and the segments up to the
middle of the scale.
The bar graph also has a zoom function, as described
under "Zoom Mode".
HiRes Mode (Model 87)
31
Zoom Mode (Power Up Option Only)
To use the Rel Zoom Bar Graph:
1. Hold down F while turning the Meter on. The
display reads “2rEL”.
2. Select the relative mode by pressing F
again.
3. The center of the bar graph now represents zero
and the sensitivity of the bar graph increases by
a factor of 10. Measured values more negative
than the stored reference activate segments to
the left of center; values more positive activate
segments to the right of center.
Uses for the Zoom Mode
The relative mode, combined with the increased
sensitivity of the bar graph's zoom mode, helps you make
fast and accurate zero and peak adjustments.
For zero adjustments, set the Meter to the desired
function, short the test leads together, press F; then
connect the leads to the circuit under test. Adjust the
circuit's variable component until the display reads zero.
Only the center segment on the zoom bar graph is lit.
For peak adjustments, set the Meter to the desired
function, connect the leads to the circuit under test; then
press F. The display reads zero. As you adjust for a
positive or negative peak, the bar graph length increases
to the right or left of zero. If an overange symbol lights
(< >), press F twice to set a new reference; then
continue with the adjustment.
HiRes Mode (Model 87)
On a Model 87 Meter, pressing H for one second causes
the Meter to enter the high-resolution (HiRes), 4-1/2 digit
mode. Readings are displayed at 10 times the normal
resolution with a maximum display of 19,999 counts. The
HiRes mode works in all modes except capacitance,
frequency counter functions, temperature, and the 250 µs
(peak) MIN MAX modes.
To return to the 3-1/2 digit mode, press H again for one
second.
80 Series V

32
MIN MAX Recording Mode
The MIN MAX mode records minimum and maximum
input values. When the inputs go below the recorded
minimum value or above the recorded maximum value,
the Meter beeps and records the new value. This mode
can be used to capture intermittent readings, record
maximum readings while you are away or record readings
while you are operating the equipment under test and
cannot watch the Meter. MIN MAX mode can also
calculate an average of all readings taken since the MIN
MAX mode was activated. To use MIN MAX mode, refer
to the functions in Table 7.
Response time is the length of time an input must stay at
a new value to be recorded. A shorter response time
captures shorter events, but with decreased accuracy.
Changing the response time erases all recorded
readings. Model 83 has 100 millisecond response time;
Model 87 has 100 millisecond, and 250 µs (peak)
response times. The 250 µs response time is indicated by
"p" on the display.
The 100 millisecond response time is best for recording
power supply surges, inrush currents, and finding
intermittent failures.
The true average value (AVG) displayed in the 100 ms
mode is the mathematical integral of all readings taken
since the start of recording (overloads are discarded).
The average reading is useful for smoothing out unstable
inputs, calculating power consumption, or estimating the
percentage of time a circuit is active.
Min Max records the signal extremes lasting longer than
100 ms.
Peak records the signal extremes lasting longer than 250
µs.
Smooth Feature (Power Up Option Only)
When the input signal changes rapidly, “smoothing”
provides a steadier reading on the display.
To use the smooth feature:
1. Hold down C while turning the Meter on. The
display will read “5___” until C is released.
2. The smooth icon (g) will appear on the left side
of the display to let you know that smoothing is
active.

Press Fagain to exit this mode.
In relative mode, the reading shown is always the
difference between the present reading and the stored

Maintenance
XWWarning
To avoid possible electric shock or personal
injury, repairs or servicing not covered in
this manual should be performed only by
qualified personnel as described in the
80 Series V Service Information
.
General Maintenance
Periodically wipe the case with a damp cloth and mild
detergent. Do not use abrasives or solvents.
Dirt or moisture in the terminals can affect readings and
can falsely activate the Input Alert feature. Clean the
terminals as follows:
1. Turn the Meter off and remove all test leads.
2. Shake out any dirt that may be in the terminals.
3. Soak a new swab with a cleaning and oiling agent
(such as WD-40). Work the swab around in each
terminal. The oiling agent insulates the terminals
from moisture-related activation of the Input Alert
feature.
Fuse Test
If a test lead is plugged into the mA/µA or A terminal and
the rotary switch is turned to a non-current function, the
Meter chirps and flashes “LEAd” if the fuse associated
with that current terminal is good. If the Meter does not
chirp or flash “LEAd”, the fuse is bad and must be
replaced. Refer to Table 8 for the appropriate
replacement fuse.
To test the quality of the fuse:
before measuring current, test the appropriate fuse as
shown in Figure 10. If the tests give readings other than
those shown, have the Meter serviced.
XWWarning
To avoid electrical shock or personal injury,
remove the test leads and any input signals
before replacing the battery or fuses. To
prevent damage or injury, install ONLY
specified replacement fuses with the
amperage, voltage, and speed ratings shown
in Table 8.

Detailed Specifications
For all detailed specifications:
Accuracy is given as ±([% of reading] + [number of least significant digits]) at 18° C to 28° C, with relative humidity up to
90 %, for a period of one year after calibration.
For Model 87 in the 4 ½-digit mode, multiply the number of least significant digits (counts) by 10. AC conversions are ac-
coupled and valid from 3 % to 100 % of range. Model 87 is true rms responding. AC crest factor can be up to 3 at full scale, 6
at half scale. For non-sinusoidal wave forms add -(2 % Rdg + 2 % full scale) typical, for a crest factor up to 3.

1. Below 10 % of range, add 12 counts.
2. The Meter is a true rms responding meter. When the input leads are shorted together in the ac functions, the Meter may display a residual
reading between 1 and 30 counts. A 30 count residual reading will cause only a 2-digit change for readings over 3 % of range. Using REL to
offset this reading may produce a much larger constant error in later measurements.
3. Frequency range: 1 kHz to 2.5 kHz.
4. A residual reading of up to 13 digits with leads shorted, will not affect stated accuracy above 3 % of range.
5. Specification increases from -1% at 200 Hz to -6% at 440 Hz when filter is in use.

1. AC conversion for Model 83 is ac coupled and calibrated to the rms value of a sine wave input.
2. AC conversions for Model 87 are ac coupled, true rms responding, and valid from 3 % to 100 % of range, except 400 mA range (5 %
to 100 % of range) and 10 A range (15 % to 100 % or range).
3. Model 87 is a true rms responding meter. When the input leads are shorted together in the ac functions, the Meter may display a
residual reading between 1 and 30 counts. A 30 count residual reading will cause only a 2 digit change for readings over 3 % of
range. Using REL to offset this reading may produce a much larger constant error in later measurements
