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”.

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.

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 “bAtt” the
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 Ω and 00.5 Ω. 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 kΩ and 1.005 kΩ. 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

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.

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.
4. Replace the Meter's top case and turn the rotary knob to OFF. (See “Reassembling
the Meter Case).

Meter Buttons Used in the Calibration Steps
The Meter buttons behave as follows when performing the Calibration Adjustment
Procedure. This may be of help determining why a calibration step is not accepted and for
determining the input value without referring to Table 16.
Press and hold to show the measured value. The measurement value is not
A
calibrated so it may not match the input value. This is normal.
B
G
Press and hold to display the required input amplitude.
Press and hold to display the frequency of the required input.
Press to store the calibration value and advance to the next step. This button
is also used to exit calibration mode after the calibration adjustment
sequence is complete.
D
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.
