XWWarning  
To avoid possible electric shock or personal injury, inspect the  
test leads for damaged insulation or exposed metal. Check the  
test leads for continuity. Replace damaged test leads before  
using the Meter.  
Precautions and Safety Information  
In this manual, a Warning identifies conditions and actions that pose hazard(s) to the  
user; a Caution identifies conditions and actions that may damage the Meter or the test  
instruments.  
XWWarning  
To avoid possible electric shock or personal injury, follow these  
guidelines:  
Use this Meter only as specified in this manual or the  
protection provided by the Meter might be impaired.  
Do not use the Meter if it is damaged. Before using the  
Meter, inspect the case. Look for cracks or missing plastic.  
Pay particular attention to the insulation surrounding the  
connectors.  
Make sure the battery door is closed and latched before  
operating the Meter.  
Replace the battery as soon as the battery indicator (M)  
appears.  
Remove test leads from the Meter before opening the  
battery door.  
Inspect the test leads for damaged insulation or exposed  
metal. Check the test leads for continuity. Replace damaged  
test leads before using the Meter.  
Do not apply more than the rated voltage, as marked on the  
Meter, between the terminals or between any terminal and  
earth ground.  
Never operate the Meter with the cover removed or the case  
open.  
Use caution when working with voltages above 30 V ac rms,  
42 V ac peak, or 60 V dc. These voltages pose a shock  
hazard.  
Use only the replacement fuses specified in this manual.  
Use the proper terminals, function, and range for  
measurements.  
Avoid working alone.  
When measuring current, turn off circuit power before  
connecting the Meter in the circuit. Remember to place the  
Meter in series with the circuit.

Digital Multimeter  
Precautions and Safety Information  
When making electrical connections, connect the common  
test lead before connecting the live test lead; when  
disconnecting, disconnect the live test lead before  
disconnecting the common test lead.  
Do not use the Meter if it operates abnormally. Protection  
may be impaired. When in doubt, have the Meter serviced.  
Do not operate the Meter around explosive gas, vapor, or  
dust.  
Use only a single 9 V battery, properly installed in the Meter  
case, to power the Meter.  
When servicing the Meter, use only specified replacement  
parts.  
When using probes, keep fingers behind the finger guards  
on the probes.  
Do not use the Low Pass Filter option to verify the presence  
of hazardous voltages. Voltages greater than what is  
indicated may be present. Make a voltage measurement  
without the filter to detect the possible presence of  
hazardous voltage, then select the filter function.  
XCaution  
To avoid possible damage to the Meter or to the equipment  
under test, follow these guidelines:  
Disconnect circuit power and discharge all high-voltage  
capacitors before testing resistance, continuity, diodes, or  
capacitance.  
Before measuring current, check the Meter's fuses.  
See " Testing the Fuses”.

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.

Accessing the PCA and Replacing the LCD  
Once the case has been opened, the A1 Main PCA can easily be removed. The shields  
disconnect from the PCA as follows:  
1. Remove the five Phillips-head screw securing the top and bottom shields to the PCA.  
2. Remove the top shield assembly that also houses the LCD and lightpipe for the LCD  
backlight.  
3. To access the LCD, unsnap the LCD mask using a small flat-blade screwdriver. The  
LCD may now be removed. Refer to Figure 2.  
Note  
Two elastomeric connectors make electrical contact between the LCD and  
the PCA. These connectors usually stick to the LCD when it is removed. If  
the connectors are to be reused, do not handle them, as the electrical  
contact points might become contaminated. Use tweezers to remove these  
connectors.  
4. To reinstall the connectors, replace the LCD and LCD mask and lay the top shield  
face down. Install the elastomeric connector strips into the slots on the top shield.

Replacing the Battery  
Replace the battery with a 9-V battery (NEDA A1604, 6F22, or 006P).  
XWWarning  
To avoid false readings, which could lead to possible electric  
shock or personal injury, replace the battery as soon as the  
battery indicator (b) appears. If the display shows bAttthe  
Meter will not function until the battery is replaced.  
Replace the battery as follows, refer to Figure 1:  
1. Turn the rotary knob to OFF and remove the test leads from the terminals.  
2. Remove the battery door by using a standard-blade screwdriver to turn the battery  
door screws one-quarter turn counterclockwise.  
3. Remove the old battery and replace it with a new one.  
4. Align the battery leads so that they not pinched between the battery door and the case  
bottom.  
5. Secure the door by turning the screws one-quarter turn clockwise.  
Testing Fuses and Current Circuitry  
If a test lead is plugged into the mA/µA or A terminal and the rotary knob 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 17 for the appropriate replacement fuse.  
After replacing the fuse, use the following procedure to verify the integrity of the new  
fuse and the current circuitry. Refer to Figure 3.  
1. Turn the rotary knob to N.  
2. To test F2, insert a test lead into the Iinput terminal and touch the probe to  
the A input terminal.  
Note  
The input receptacles contain split contacts. Be sure to touch the probe to  
the half of the receptacle nearest the LCD.  
3. The display should indicate between 00.0 and 00.5 . If the display reads OL,  
replace the fuse and test again. If the display reads another value, further servicing is  
required.  
4. To test F1, move the probe from the A input terminal to the mA/UA input terminal.  
5. The display should read between 0.995 kand 1.005 k. If the display reads OL,  
replace the fuse and test again. If the display reads another value, further servicing is  
required.  
XWWarning  
To avoid electrical shock or personal injury:  
Remove the test leads and any input signals before  
replacing the battery or fuses.  
Install ONLY specified replacement fuses with the  
amperage, voltage, and speed ratings shown in Table 17.

Performance Tests  
The following performance tests verify the complete operability of the Meter and check  
the accuracy of each Meter function against the Meter’s specifications. Performance tests  
should be performed annually to ensure that the Meter is within accuracy specifications.  
Accuracy specifications are valid for a period of one year after calibration adjustment,  
when measured at an operating temperature of 18 °C to 28 °C and at a maximum of 90 %  
relative humidity.  
To perform the following tests, it is not necessary to open the case. No adjustments are  
necessary. Make the required connections, apply the designated inputs, and determine if  
the reading on the Meter display falls within the acceptable range indicated.  
Note  
If the Meter fails any of these tests, it needs calibration adjustment or repair.

Testing the Inductive Pickup (88 Only)  
To test the inductive pickup, a function generator output will simulate automobile spark  
plug signals on a loop of wire containing a 10 eresistor. The pickup will be clamped to  
the wire and output voltage from the pickup will be monitored by an oscilloscope.  
Perform the following procedure to test the inductive pickup:  
1. Solder a 10-inch piece of 14 AWG wire to one end of a 10 e1 % resistor.  
2. Connect the other end of the 10 eresistor to the terminal LOW output of the  
function generator. Place the other end of the 14-AWG wire to the HIGH output of  
the function generator. See Figure 5.  
3. Connect a 10X scope probe from channel 2 (dc-coupled) of the oscilloscope across  
the 10 eresistor.  
4. Clamp the inductive pickup to the wire loop on the HIGH side of the resistor as  
shown in Figure 5.  
Make sure that the jaws of the inductive pickup are closed completely, and that the  
side of the inductive pickup that says "SPARK PLUG SIDE" points toward the  
HIGH output of the function generator.  
5. Connect a 10X scope probe from channel 1 (dc-coupled) of the oscilloscope across  
the output of the inductive pickup.

See Figure 6.  
10. Set the oscilloscope for 1.0 V/DIV @ 5.0 ms/DIV.  
11. Trigger the waveform on Channel 1.  
12. Check that the peak voltage is greater than 5.7 V and decays to less than 1.0 V  
between pulses. See Figure 6. Record the peak value for later use.  
13. Adjust the function generator output so the peak voltage is 6 V.  
14. Set the scope for 1.0 ms/DIV and trigger waveform.  
15. Check the amplitude after 3.0 ms from the waveform peak, the voltage amplitude is  
2.4 V +0.5/-0.8 (1.6 V to 2.9 V). (See Figure 3-5(C).)  
16. Re-adjust the function generator output to obtain the value recorded in step 12.  
17. Set the scope for 5.0 ms/DIV.  
18. Turn the inductive pickup so that "SPARK PLUG SIDE" points along the wire  
connected to the LOW output of the function generator. Check that the waveform is  
less than 2 V.

Calibration Adjustment  
Calibration Adjustment  
The Meter features closed-case calibration adjustment using known reference sources.  
The Meter measures the applied reference source, calculates correction factors and stores  
the correction factors in nonvolatile memory.  
The following sections present the features and Meter pushbutton functions that can be  
used during the Calibration Adjustment Procedure. Perform the Calibration Adjustment  
Procedure should the Meter fail any performance test listed in Table 15.  
Calibration Adjustment Counter  
The Meter contains a calibration adjustment counter. The counter is incremented each  
time a Calibration Adjustment Procedure is completed. The value in the counter can be  
recorded and used to show that no adjustments have been made during a calibration  
cycle.  
Use the following steps to view the Meter's calibration counter.  
1. While holding down B, turn the rotary knob from OFF to VAC. The Meter  
should display “ZCAL”.  
2. Press Donce to see the calibration counter. For example "n001".  
3. Turn the rotary knob to OFF.  
Calibration Adjustment Password  
To start the Calibration Adjustment Procedure, the correct 4-button password must be  
entered. The password can be changed or reset to the default as described in following  
paragraphs. The default password is “1234”.  
Changing the Password  
Use the following steps to change the Meter's password:  
1. While holding down B, turn the rotary knob from OFF to VAC. The Meter  
displays “ZCAL”.  
2. Press Donce to see the calibration counter.  
3. Press Dagain to start the password entry. The Meter displays "????".  
4. The Meter buttons represent the digit indicated below when entering or changing the  
password:  
A= 1 B= 2 C= 3 D= 4  
H= 5  
E= 6 F= 7 G= 8  
Press the 4 buttons to enter the old password. If changing the password for the first  
time, enter A(1) B(2) C(3) D(4).  
5. Press Cto change the password. The Meter displays "----" if the old password is  
correct. If the password is not correct, the Meter emits a double beep, displays "????"  
and the password must be entered again. Repeat step 4.  
6. Press the 4 buttons of the new password.  
7. Press Dto store the new password.

Restoring the Default Password  
If the calibration password is forgotten, the default password (1234) can be restored using  
the following steps.  
1. While holding down B, turn the rotary knob from OFF to VAC. The Meter  
displays “ZCAL”.  
2. Remove the Meter's top case. Leave the PCA in the bottom case. (See “Opening the  
Meter Case”.)  
XWWarning  
To avoid electrical shock or personal injury, remove the test  
leads and any input signal before removing the Meter's top  
case.  
3. Through an access hole provided in the top shield, short across the keypads on the  
PCA. See Figure 7. The Meter should beep. The default password is now restored.

Calibration Adjustment Procedure  
Use the following steps to adjust the Meter's calibration. If the Meter is turned off before  
completion of the adjustment procedure, the calibration constants are not changed.  
1. While holding down B, turn the rotary knob from OFF to VAC. The Meter  
displays “ZCAL”.  
2. Press Donce to see the calibration counter.  
3. Press Dagain to start the password entry. The Meter displays "????".  
4. Press 4 buttons to enter the password.  
5. Press Dto go to the first calibration step. The Meter displays "C-01" if the  
password is correct. If the password is not correct, the Meter emits a double beep,  
displays "????" and the password must be entered again. Repeat step 4.  
6. Using Table 16, apply the input value listed for each calibration adjustment step. For  
each step, position the rotary switch and apply the input to the terminals as indicated  
in the table.  
7. After each input value is applied, press Dto accept the value and proceed to the  
next step (C-02 and so forth).  
Notes  
After pressing D, wait until the step number advances before changing  
the calibrator source or turning the Meter rotary knob.  
If the Meter rotary knob is not in the correct position, or if the measured  
value is not within the anticipated range of the input value, the Meter emits  
a double beep and will not continue to the next step.  
Some adjustment steps take longer to execute than others (10 to 15  
seconds). For these steps, the Meter will beep when the step is complete.  
Not all steps have this feature.  
8. After the final step, the display shows "End" to indicate that the calibration  
adjustment is complete. Press Dto go to meter mode.
