You have completed adjusting the resistance of the PXIe-4081. Proceed to one of the
following sections:
•
Adjusting AC Voltage
•
Adjusting Current
If you are not performing additional adjustments, proceed to the
Completing the Adjustment
Procedures
section to commit your calibration constants.
Adjusting AC Voltages
Note
You must adjust DC voltage before you adjust AC voltage.
Note
If you do not use the AC voltage modes for any measurements, or the
accuracy of these modes is irrelevant, you can skip this section in the calibration
procedure and go directly to the Adjusting Current Modes section.
Complete the following steps to adjust the AC voltage of the device:
1.
Reset the calibrator.
2.
Connect the PXIe-4081 to the calibrator as shown in
Figure 1.
on page 6.
3.
Call the niDMM Cal Adjust Misc VI or the
niDMM_CalAdjustMisc
function with
Type
set to
NIDMM_EXTCAL_MISCCAL_VREF_AC_VOLTAGE
.
4.
Adjust the AC voltage gain with each configuration in the following table:
a)
Commit the PXIe-4081 to the specified range.
b)
Configure the calibrator as specified and allow it to settle.
c)
Call the niDMM Cal Adjust AC Filter VI or the
niDMM_CalAdjustACFilter
function with the specified parameters.
