Note
If the calibration is correctly initiated, the ‘Start Calibration’ register will automatically reset to 0. If the
instrument is unable to initiate the calibration (the instrument is in maintenance mode or already in
calibration) the register will remain at 1 and the calibration will remain pending. Setting the ‘Start
Calibration’ register to ‘0’ will remove any pending operation.
