You have completed verifying the DC current of the PXIe-4081. Select one of the following
options:
•
If you want to continue verifying other modes, go to the
Verifying AC Current
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 Current
Complete the following steps to verify AC current:
1.
Set the calibrator to
Standby
.
2.
Connect the PXIe-4081 to the calibrator using low leakage cables according to the
configuration shown in
Figure 5.
on page 16.
3.
Reset the PXIe-4081.
4.
Initialize the PXIe-4081 for AC current with a range of 100 µA and resolution of 6.5
digits.
