To verify digitize DC current accuracy:
1. Connect the Model DMM7510 and calibrator as shown in the following figure.
2. On the Model DMM7510, press the FUNCTION key, select the Digitize Functions tab, and
select Digitize Current.
3. Press the HOME key.
4. Set the Range to 1 mA.
5. Press the MENU key.
6. Select Settings.
7. Set the Sample Rate to 1000.
8. Set the Aperture to Auto or 1 ms.
9. Set the Count to 100.
Zero verify the Model DMM7510:
1. On the calibrator, select the OPR/STBY key. Ensure that the front panel displays STANDBY.
2. Verify the Model DMM7510 Zero reading for each range.
Rel the system:
1. On the calibrator, select the OPR/STBY key. Ensure that the front panel displays OPERATE.
2. Se thte calibration current output to NORMAL.
3. Set the calibrator output to 0 A and allow the reading to settle.
4. On the Model DMM7510, press the MENU key.
5. Select Calculations.
6. Select Rel Acquire.
7. Source positive and negative full-scale and half-scale currents, as listed in
Verify digitize current 1 mA range
8. Repeat these steps for the 10 mA to 3 A range settings listed in the tables below. For each
current setting, verify that the STATISTICS swipe screen reading for Average is within low and
high limits.
