12. Verify the accuracy for each configuration in the following table:
a)
Set the PXIe-4080/4082 to the specified configuration and commit.
b)
Set the calibrator to the specified configuration and allow it to settle.
c)
Acquire the specified measurement.
d)
Subtract the appropriate offset null you recorded previously and compare the result
to the limits.
e)
Repeat for each listed input resistance.
f)
Set the calibrator to
Standby
.

You have completed verifying the DC voltage mode of the PXIe-4080/4082. Select one of the
following options:
•
If you want to continue verifying other modes, go to the
Verifying AC Voltage
section.
•
If you do not want to verify any additional modes, and you are performing a pre-
adjustment verification, close the session.
•
If you do not want to verify any additional modes, and you want to update the verification
time stamp, complete the following steps:
1.
Open a new calibration session to the instrument (with correct calibration password).
2.
Close the calibration session with the
Action
set to
Save
.
Verifying AC Voltage
Complete the following steps to verify AC voltage:
1.
Set the calibrator to
Standby
mode.
