Note Apply an offset null to the 100 kΩ measurement by subtracting the
corresponding 0 Ω measurement in the 100 kΩ range.
You have completed verifying the 4-wire resistance mode of the PXIe-4080/4082. Select one
of the following options:
•
If you want to continue verifying other modes, go to the Verifying 2-Wire Resistance
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 2-Wire Resistance
Complete the following steps to verify 2-wire resistance:
1.
Plug in the shorting bar across the HI and LO terminals on the PXIe-4080/4082.
