4(/&. Press ! to return to the Display Loop. This
will not overwrite any user settings but will erase the controller
calibration values. This procedure does not require any
calibration signals nor external meters. This can be used to clear
calibration error flag
'.4#.
CAUTION: This procedure will result in up to ±10% reading
error and the controller will no longer be within factory
specifications. For this reason, this procedure should only be
performed if meter error is outside of this range to temporarily
restore operation until the unit can be accurately calibrated.
