Issue Details

My SMU keeps failing self-calibration and throws error 1074118575 which mentions that the device has activated Overload Protection (OLP).


To get an SMU out of Overload Protection, reset the device in NI MAX and check that it passes a self-test and the self-calibration.

If the device cannot be reset or fails the test or calibration, an external calibration or repair might be needed.
