Exposure Calibration IMPORTANT!:You should not attempt to recalibrate the meter yourself. Recalibration of the meter requires both an equipped calibration laboratory and an intimate knowledge of the internal workings of the instrument. A recalibration and maintenance service is available from Spectra Cine, Inc. or an authorized service center for a nominal charge. There are no user-serviceable components inside the meter. Opening the meter will void your warranty. The meter is equipped with an indicator which will signal if the cover has been removed by other than factory authorized personnel.
