5.2 Turn off the meter and take off the holster. Loosen the screw on the battery door and slide the cover away from the instrument. 5.3 Replace the old battery with a new 9V battery and reinstate the cover and holster. 7.4 The sensitivity of the light sensor will decrease due to the service conditions as luminous intensity and time. To maintain the basic accuracy, regular calibration is recommended. 6. SPECTRAL SENSITIVITY CHARACTERISTIC: 8. RECOMMENDED ILLUMINATION: 7. MAINTENANCE 7.
