Testing the AC Voltage Function
To verify accuracy in the ac voltage ranges, do the following:
1. Connect the Calibrator to the
z and COM inputs on the Meter.
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
Series III model (83, 85, or 87) shown in Table 4.
If the display reading falls outside of the range shown in Table 4, the Meter does not
meet specification.
4. Repeat this procedure for steps 2 through 17 of Table 4.
