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 1-2 in Table 10.
4. For each input, compare the readings on the Meter display to the display readings in
Table 10.
5. If the display reading falls outside of the range shown in Table 10, the meter does not
meet specification.

6. Press the blue button on the Meter to toggle to the AC amp measurement function.
7. Apply the inputs for steps 1-4 in Table 11.
8. For each input, compare the reading on the Meter display to the display readings 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 VΩ 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 1-5 of Table 12.
4. Compare the reading on the Meter display with the display reading shown in Table 12.
5 If the display reading falls outside of the range shown in Table 12, the Meter does not
meet specification.
