6. Adjust the capacitance and inductance calibration with each standard in the following
table:
a)
Plug the specified resistor between the HI and LO terminals of the PXIe-4082. The
leads between the resistor and the PXIe-4082 should be ≤ 1 inch.
b) Wait 30 seconds for thermal EMF to stabilize.
c) Call the niDMM Cal Adjust LC VI or the
niDMM_CalAdjustLC
function with
the specified Type parameter.
Value of Resistor niDMM Cal Adjust LC Parameter - Type
25 Ω
NIDMM_EXTCAL_LC_25OHM
125 Ω
NIDMM_EXTCAL_LC_125OHM
5 kΩ
NIDMM_EXTCAL_LC_5KOHM
100 kΩ
NIDMM_EXTCAL_LC_100KOHM
You have completed adjusting the capacitance and inductance modes of the PXIe-4082.
Proceed to the
Completing the Adjustment Procedures section to commit the calibration
constants.
Completing the Adjustment Procedures
To complete the adjustment procedure for the PXIe-4080/4082 and close the session, call the
niDMM Close Ext Cal VI or the
niDMM_CloseExtCal
function with the following
parameter:
•
Action =
NIDMM_EXTCAL_ACTION_SAVE
if you want to save the new calibration
coefficients to the device. Otherwise,
• Action =
NIDMM_EXTCAL_ACTION_ABORT
if you want to restore the original calibration
coefficients to the device.
Reverification
Repeat the Verification section to determine the as-left status of the PXIe-4080/4082.
Note If any test fails reverification after performing an adjustment, verify that you
have met the test conditions before returning your PXIe-4080/4082 to NI. Refer to
the
Worldwide Support and Services section for information about support resources
or service requests.
