Testing Millivoltage (mV) Function
To verify accuracy of the
mV
function, do the following.
1. Connect the Calibrator to the
V
Ω
and
COM
inputs on the meter.
2. Turn the rotary switch to
mV
3. Set the calibrator for the voltage and frequency from step 1 to 4 in Table 3.
4. Compare the reading on the Meter display with the display reading in Table 3.
5. If the display reading falls outside of the range shown in Table 3, the Meter does not
meet specification.

Input
Reading
Step Voltage Frequency
1 10.000mV 60Hz 9.850
to
10.150
2 10.000mV 1KHz 9.820
to
10.180
3 100.00mV 60Hz 98.50
to
100.15
4 100.00mV 1KHz 98.20
to
100.20
6. Press the blue button on the Meter to toggle to
DC mV
function.
7. Set the calibrator for the voltage from step 1 to 2 in Table 4.
8. Compare the reading on the Meter display with the display reading in Table 4.
9. If the display reading falls outside of the range shown in Table 3, the Meter does not
meet specification.

Testing the PEAK HOLD Function
To check
PEAK HOLD
feature, do the following:
1. Connect the Calibrator to the
V
Ω
and
COM
inputs on the Meter.
2. Apply 1.0V AC at 60Hz from the Calibrator to the
V
Ω
and
COM
inputs on the Meter.
3. Turn the rotary switch to
V
Note:
The RMS converter is not used in Peak Hold mode. The digital display represents
the actual peak value of the input.
4. Press
PEAK H
and then
M/M/A
5. The reading on sub-display should be within 1.441 (Max) and -1.441 (MIN).
6. Press
PEAK H
to escape.
Testing the Resistance Function
To verify the accuracy of the resistance function, do the following:
1. Connect the Calibrator to
V
Ω
and
COM
on the Meter.
2. Turn the rotary switch to
Ω
3. Apply the inputs for steps 1 - 7 in Table 5.
4. Compare the Meter display readings to the readings in Table 5.
Note:
Press
RANGE
on the Meter to enter the 200M
Ω
and 2G
Ω
ranges. Then
proceed with steps 8 - 9 in Table 5. Compare the meter display readings to the
readings in Table 5.
5. If the display reading falls outside of the range shown in Table 5, the meter does not meet specification.
