Example Restores factory calibration for SMU A:
smua.cal.restore(smua.CALSET_FACTORY)
smuX.cal.save
Function Stores the calibration constants in non-volatile memory.
Usage
smuX.cal.save()
Remarks • This function will store the current set of calibration constants in non-volatile memory. The
previous calibration constants (from the default calibration set) will be copied to the
previous calibration set (smuX.CALSET_PREVIOUS) prior to overwriting the default
calibration set.

of the calibration constants have been changed, this function will be disabled, unless the
calibration adjust date has been set.
