You have completed verifying the 2-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 DC Current
section.
•
If 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 DC Current
Complete the following steps to verify DC current:
1.
Unplug all cables from the PXIe-4080/4082.
2.
Reset the PXIe-4080/4082.
3.
Initialize the PXIe-4080/4082 for DC current with a range of 20 mA and resolution of 6.5
digits.
4.
Verify the accuracy for each configuration in the following table:
a)
Acquire the measurement at each specified range.
b)
Compare to the specified limits.
