Model DMM7510 7½ Digit Graphical Sampling Multimeter Calibration Manual
Verify the digitize voltage 100 mV to 1000 V ranges
Use shielded low-thermal connections when testing the 100 mV and 1 V ranges to avoid errors
caused by noise or thermal effects. Connect the shield to the output LO terminal of the calibrator.
To verify digitize voltage accuracy:
1. Connect the Model DMM7510 HI and LO INPUT connectors to the calibrator as shown in the
following figure.
2. On the Model DMM7510, press the FUNCTION key, select the Digitize Functions tab, and
select Digitize Voltage.
3. Press the HOME key.
4. Select Range and select 100 mV.
5. Press the MENU key.
6. Select Settings.
7. Set the Sample Rate to 1000.
8. Set the Aperture to Auto.
9. Set the Count to 100.
10. Set the calibrator output to 0.00000 mVDC and allow the reading to settle.
11. Press the MENU key.
12. Select Calculations.
13. Select Rel Acquire.
14. Source positive and negative full-scale and half-scale voltages, as listed in
voltage 100 mV range
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.
