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.
