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. Select Rel Acquire.
13. Source positive and negative full-scale and half-scale voltages, as listed in the following table.
Verify the 1 V 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.
