WTest lead alert. Displayed when the test leads are in the A or mA/A terminal and the selected rotary switch position does not correspond to the terminal being used. Making Measurements 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/A 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. 13 80 Series V Users Manual When measuring voltage, the Meter acts approximately like a 10 M (10,000,000 ) 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 k (10,000 ) 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.

Measuring AC and DC Voltage 14 Making Measurements XWWarning 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. 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 measurement without the filter to detect the possible presence of hazardous voltage. Then, select the filter function. 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 A AC, or 18 A 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. 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. 1 kHz 100 Hz aom11f.eps Figure 3. Low Pass Filter 15 80 Series V Users Manual 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. 16 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. Making Measurements For in-circuit tests, turn circuit power off. 87 V TRUE RMS MULTIMETER Activates continuity beeper 87 V TRUE RMS MULTIMETER C/F MIN MAX RANGE C/F AutoHOLD MIN MAX Peak MIN MAX Hz % REL 41/2 DIGITS 1 Second mV Hz % mV mA A A V OFF A AutoHOLD 41/2 DIGITS 1 Second V LO RANGE Peak MIN MAX REL mA A V ON (closed) A V LO OFF (open) OFF mA A 10A MAX FUSED COM 400mA FUSED V A mA A 10A MAX FUSED COM V 400mA FUSED aom4f.eps Figure 4. Testing for Continuity 17 80 Series V Users Manual 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 , 6.000 k, 60.00 k, 600.0 k, 6.000 M, and 50.00M. To measure resistance, set up the Meter as shown in Figure 5. 18 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 to 0.2 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. Refer to Table 18.

Measuring Resistance 19 80 Series V Users Manual 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 M, 1/1 nS = 1,000 M. 20 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. Making Measurements 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. 87 V Select Capacitance TRUE RMS MULTIMETER C/F MIN MAX RANGE AutoHOLD Peak MIN MAX Hz % REL 41/2 DIGITS 1 Second mV mA A V A V LO OFF The Meter's capacitance ranges are 10.00 nF, 100.0 nF, 1.000 F, 10.00 F, 100.0 F, and 9999 F. To measure capacitance, set up the Meter as shown in Figure 6. A mA A 10A MAX FUSED COM V 400mA FUSED 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.

Measuring Capacitance 21 80 Series V Users Manual 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. 22 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 forwardbias 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.

Testing a Diode 23 80 Series V Users Manual 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. 24 The Meter's current ranges are 600.0 A, 6000 A, 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 highvoltage 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/A 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/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.

Measuring Current 25 80 Series V Users Manual If you are using the A terminal, set the rotary switch to mA/A. If you are using the mA/A terminal, set the rotary switch to A for currents below 6000 A (6 mA), or mA/A for currents above 6000 A. 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". 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. 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. 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 (A, mA, or A). 7. Turn off power to the circuit and discharge all highvoltage capacitors. Remove the Meter and restore the circuit to normal operation. 3. 26 Making Measurements Measuring Frequency The following are some tips for 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. * 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. 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. 27 80 Series V Users Manual Table 6.

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. 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. To measure duty cycle, set up the Meter to measure frequency; then press Hz a second time. As with the +Slope Trigger Point -Slope Trigger Point 30% Above +Slope 70% Below -Slope 100% iy3f.eps Figure 9. Components of Duty Cycle Measurements 29 80 Series V Users Manual 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". 30 HiRes Mode (Model 87) 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 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 s (peak) MIN MAX modes. To return to the 3-1/2 digit mode, press H again for one second. 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 31 80 Series V Users Manual 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 s (peak) response times. The 250 s 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). 32 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 s. 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. Smooth Feature (Power Up Option Only) Table 7. MIN MAX Functions Button B B (while in MIN MAX mode) E PEAK MIN MAX D B (hold for 1 second) MIN MAX Function Enter MIN MAX recording mode. The Meter is locked in the range displayed before you entered MIN MAX mode. (Select the desired measurement function and range before entering MIN MAX.) The Meter beeps each time a new minimum or maximum value is recorded. Step through maximum (MAX), minimum (MIN), average (AVG) and present values. Model 87 only: Select 100 ms or 250 s response time. (The 250 s response time is indicated by pon the display.) Stored values are erased. The present and AVG (average) values are not available when 250 s is selected. Stop recording without erasing stored values. Press again to resume recording. Exit MIN MAX mode. Stored values are erased. The Meter stays in the selected range. 33 80 Series V Users Manual AutoHOLD Mode XWWarning To avoid possible electric shock or personal injury, do not use AutoHOLD mode to determine that circuits are without power. The AutoHOLD mode will not capture unstable or noisy readings. The AutoHOLD mode captures the present reading on the display. When a new, stable reading is detected, the Meter beeps and displays the new reading. To enter or exit AutoHOLD mode, press D. 34 Relative Mode Selecting relative mode ( F) causes the Meter to zero the display and store the present reading as the reference for subsequent measurements. The Meter is locked into the range selected when you pressed F. Press Fagain to exit this mode. In relative mode, the reading shown is always the difference between the present reading and the stored reference value. For example, if the stored reference value is 15.00 V and the present reading is 14.10 V, the display shows -0.90 V. Maintenance Fuse Test 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. If a test lead is plugged into the mA/A 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.
