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

.
7. Set the calibration for the current from step 1 - 2 in Table 6.
8. For each input, compare the reading on the Meter display to the reading in Table 6.
9. If the display reading falls outside of the range shown in Table 6, 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
Hz
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 Calibrator for the sine wave voltage and frequency for steps 1-5 of Table 8.
4. Compare the reading on the Meter display with the display reading shown in Table 8.
5. If the display reading falls outside of the range shown in Table 8, the Meter does not meet specification.
