Does the accelerometer that you want to calibrate require a constant current excitation (ICP or similar)? If it is the case the calibration VI does not provide a way to turn on ICP on the 4472. You will need to do a separate call to AI Parameters.
Would you mind posting your code? You can also email it to me directly at thierry.debelle@ni.com. That should help us to make progress faster. Thanks in advance.
