4. Set up the Model DMM7510 to the Digitize DC current function.
5. Press the
HOME
key.
6. Set the Range to
10 µA
.
7. Press the
MENU
key.
8. Select
Settings
.
9. Set the Sample Rate to
1000
.
10. Set the Aperture to
Auto
.
11. Set the Count to
100
.
Zero verify the Model 7510:
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 Voltage
,
2 V
range.
3. Set the calibrator to
0 V
.
4. Rel the Model DMM7510.
5. Zero Range the reference DMM system offset.
6. Set the calibrator to source the voltage identified in the following "10 µA and 100 µA range
verification" table, verifying the Model DMM7510 accuracy from the calculated reference DMM
Voltage/Characterized shunt.
For each setting, verify that the STATISTICS swipe screen reading
for Average is within low and high limits.
7. For 100 µA verification, set the reference DMM to the 20 V range.
8. Repeat steps 3 to 6 for 100 µA verification.
