7. Update the output calibration constants by configuring and calling the niDCPower Cal
Adjust Voltage Level VI or niDCPower_CalAdjustVoltageLevel function.
a) Input the DMM 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.
