To verify ac voltage accuracy for the 750 V range:
1. Put the calibrator in Standby.
2. Connect the DMM6500 HI and LO INPUT connectors to the calibrator as shown in the following
figure.
3. For 750 V at 50 kHz and 100 kHz outputs, connect the calibrator to the Fluke 5725A amplifier.

4. On the DMM6500, press the FUNCTION key and select AC voltage.
5. On the home screen, select the button next to Range and select 750 V.
6. Press the MENU key.
7. Under Measure, select Settings.
8. Ensure that detector bandwidth is set to 30 Hz.
AC voltage is specified for the detector bandwidth setting of 3 Hz. Three Hz measures accurately for
input signals from 3 Hz to 300 kHz, with reading rates ≈ 2 readings/s. To improve verification
throughput to ≈ 200 readings/s, set detector bandwidth to 30 Hz for frequencies of 30 Hz to 300 kHz.
To verify frequencies 1 kHz and higher, set the detector bandwidth to 300 Hz for faster ≈ 200
readings/s throughput.
