To verify digitize voltage accuracy:
1. Connect the DMM6500 HI and LO INPUT connectors to the calibrator as shown in the following
figure.
Figure 4: Connections for digitize voltage verification 100 mV to 1000 V ranges
2. On the DMM6500, press the FUNCTION key, select the Digitize Functions tab, and select
Digitize Voltage.
3. On the home screen, select the button next to Range and select 100 mV.
4. Press the MENU key.
5. Under Measure, select Settings.
6. Set the Sample Rate to 1000.
7. Set the Aperture to Auto.
8. Set the Count to 100.
9. Set the calibrator output to 0.00000 mV dc and allow the reading to settle.
10. Press the MENU key.
11. Under Measure, select Calculations.
12. Source positive and negative full-scale and half-scale voltages, as listed in the following table.
Verify the 100 mV to 100 V range settings listed in the tables below. For each voltage setting,
verify that the STATISTICS swipe screen reading for Average is within low and high limits.
The Fluke 5720A or 5730A calibrator 1000 V range 0.0 V setting is not verified.
