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 the
tip 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.
