Testing the Amp (A) Function
To verify the accuracy in the ampere (A) measurement function, do the
Following:
1. Connect the Calibrator to the
A
and
COM
inputs of the Meter.
2. Turn the rotary switch to
A
3. Apply the inputs for steps 1 - 6 in Table 10.
4. For each input, compare the readings on the Meter display to the readings
in Table 10.
5. If the display reading falls outside of the range shown in Table 10, the meter does not
meet specification.

measurement function.
7. Apply the inputs for steps 1 - 2 in Table 11.
8. For each input, compare the reading on the Meter display to the readings for
your meter in Table 11.
9. If the display reading falls outside of the range shown in Table 11, the meter does not
meet specification.

Testing the Frequency Function
To verify the accuracy of the Meter’s frequency function, do the following:
1. Connect the Calibrator to the
V
Ω
and
COM
inputs on the Meter.
Note
The accuracy of the Calibrator’s frequency function must be appropriate
for the specified accuracy of the Meter.
2. Set the rotary switch to
Hz
.
3. Set the Function Generator for the square wave voltage and frequency
for steps 1 - 6 of Table 12.
