BATTERY CHECK-UP & REPLACEMENT
1.
As the battery power is not sufficient, LCD will display low battery, and replacement of one new
battery is required.
2.
After turning off the meter, disconnect the battery cover with a screwier.
3.
Disconnect the battery from the instrument and replace it with a standard 9V battery and go for the
cover.
SPECTRAL SENSITIVITY CHARACTERISTIC
¾
To the detector, the applied photo diode with filters makes the spectral sensitivity characteristic
almost meet C.I.E.(INTERNATIONAL COMMISSION ON ILLUMINATION) Photo curve V (λ)
as the following chart described.
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.
