MAINTENANCE

1. The white plastic disc on the top of the detector should be cleaned with a damp cloth when necessary.

2. Do not store the instrument where temperature or humidity is excessively high.

3. The reference level, as marker on the face plate, is on the top of the photo detector globe.

4. The calibration interval for the photo detector will vary according to operational conditions, but generally the sensitivity decreases in direct proportion to the product of luminous intensity by the operational time. In order to maintain the basic accuracy of the instrument, periodic calibration is recommended.
