Adjusting Residual Voltage Offset
Eliminate residual offset voltage at 0 V by configuring and calling the niDCPower Cal Adjust
Residual Voltage Offset VI or
niDCPower_CalAdjustResidualVoltageOffset
function.
Closing the Adjustment Session
Close the session and commit the new constants to hardware by calling the niDCPower Close
External Calibration VI or
niDCPower_CloseExtCal
function and specifying Commit as
the
calibration close action
.
Alternative to Performing Adjustment Procedures
If your device passes all as-left limits in the verification procedures successfully and you want
to skip updating the calibration constants, you can update solely the calibration date by
completing the following steps.
Note
NI recommends following all adjustment procedures in order to update the
calibration constants and renew the device calibration interval.
1.
Call either the niDCPower Initialize External Calibration VI or the
niDCPower_InitExtCal
function.
2.
Call either the niDCPower Close External Calibration VI or the
niDCPower_CloseExtCal
function, specifying Commit in
calibration close action
.
Reverification
section to determine the as-left status of the PXIe-4135.
Note
If any test fails reverification after performing an adjustment, verify that you
have met the test conditions before returning your PXIe-4135 to NI. Refer to the
Worldwide Support and Services
section for information about support resources or
service requests.

Setting the Calibration Due Date
Use either Measurement Automation Explorer (MAX) or NI System Configuration API to set
a calibration due date for the device or to clear the calibration due date. NI suggests a
minimum calibration due date of the date of external calibration plus the external calibration
interval for the device.
