10. MAINTENANCE

•  The white plastic disc on the top of the detector should be cleaned with 

a damp cloth when necessary.

•  Do not store the instrument where temperature or humidity is 

excessively high.

•  The reference level, as marker on the face plate, is the tip of the photo 

detector globe.

•  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.
