• 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-4080/4082 to the calibrator using low leakage cables as shown in
Figure 4. on page 15.
3. Reset the PXIe-4080/4082.
4. Initialize the PXIe-4080/4082 for AC Current with a range of 10mA and a resolution of
6.5 digits.
5. Verify the accuracy for each configuration in the following table:
a)
Set the PXIe-4080/4082 to the listed configuration and commit.
b) Set the Calibrator to the listed configuration and allow it to settle.
c) Acquire the specified measurement and compare to the limits.
d) Set the calibrator to
Standby
if you have completed all test points in a DMM
Range.
