Testing the AC Voltage Function

To verify accuracy in the ac voltage ranges, do the following:
1. Connect the Calibrator to the
2. Set the Calibrator for the voltage and frequency called for in step 1 of Table 4.
3. Compare the reading on the Meter display with the display reading for your 80
4. Repeat this procedure for steps 2 through 17 of Table 4.
