1. Set the first specified level range, limit range, and limit on the NI 4112.
2. Set the level on the NI 4112 to the first specified test point.
3. Take a current measurement using the DMM, and take a current measurement using the
NI 4112.
4. Store the values from the previous step as inputs for the niDCPower Cal Adjust VI or
function called in the following steps.
5. Repeat the previous three steps for each test point specified in the level range.
6. Update the measurement calibration constants by configuring and calling the niDCPower
Cal Adjust Current Measurement VI or
niDCPower_CalAdjustCurrentMeasurement function.
a) Input the DMM measurements as the measured outputs.
b) Input the NI 4112 measurements as the reported outputs.
c) Input the specified level range as the range.
7. Update the output calibration constants by configuring and calling the niDCPower Cal
Adjust Current Limit VI or niDCPower_CalAdjustCurrentLimit function.
a) Input the calculated shunt current measurements as the measured outputs.
b) Input the test points as the requested outputs.
c) Input the specified level range as the range.
8. If more than one level range is specified, repeat the previous steps using the values
specified in each level range.

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.
Reverification
Repeat the Verification section to determine the as-left status of the device.
Note If any test fails reverification after performing an adjustment, verify that you
have met the Test Conditions before returning your device to NI. Refer to the
