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

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
After completing adjustment, wait a minimum of five minutes for the internal device
temperature to stabilize. Repeat the
section to determine the as-left status of the
device.
Note
If any test fails reverification after performing an adjustment, verify that you
before returning your PXIe-4139 to NI. Refer to the
