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. Set the reference DMM to
DC Current, 2 mA
range.
3. Set the calibrator to source zero current.
4. Rel the Model DMM7510.
5. Zero Range the reference DMM for system offset.
6. Set the calibrator to source the current identified in the 1 mA verification, verifying the Model
DMM7510 accuracy from the calculated reference DMM current.
7. For 10 mA verification, set the reference DMM to the 20 mA range.
8. Repeat steps 1 to 6 for 10 mA verification.
Verify DC current 1 mA and 10 mA range
