You have completed verifying the capacitance and inductance of the PXIe-4082. Select one of
the following options:
• If you are performing a pre-adjustment verification, close the session.
• 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

Adjustment

This section explains how to adjust the PXIe-4080/4082. You can choose to perform these
adjustment procedures with or without performing the verification procedure first.
Note Repeat the verification procedures after you perform these adjustment
procedures. NI recommends that you perform a post-adjustment verification to
ensure that the device you have calibrated is operating within specifications after
adjustments.
