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
(on page 2-18). 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.
