2. Set the niDCPower Output Function property or
NIDCPOWER_OUTPUT_FUNCTION
attribute to DC Voltage for the NI 4141.
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.
Adjusting Residual Current Offset
1. Disconnect all equipment from the output of the NI 4141.
2. Eliminate offset current at 0 A by configuring and calling the niDCPower Cal Adjust
Residual Current Offset VI or
niDCPower_CalAdjustResidualCurrentOffset
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 Adjustment Procedures
If your device passes all 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 one of the following:
•
niDCPower Initialize External Calibration VI
•
niDCPower_InitExtCal
function
