2.
Connect the PXIe-4080/4082 to the calibrator using low leakage cables, as shown in
on page 6.
3.
Reset the PXIe-4080/4082.
4.
Initialize the PXIe-4080/4082 for AC Voltage with a range of 50 mV and 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 the result to the limits.
d)
Repeat for each listed coupling.
e)
Set the calibrator to
Standby
