4. Operation instructions
1. First the battery has to be connected, then the button
“ON” has to be pressed.
2. The range selection switch has to be pressed to the
desired range.
3. The photo detector cap has to be removed and faced to
the light source in a horizontal position.
4. Now the test value can be read from the display.
5. Over range means: if the instrument only displays “1” in
the LCD, the input signal has been too strong and a higher
range should be selected.
6. Data-Hold mode: the HOLD- key (also ON/OFF-key)
has to be pressed to select the HOLD mode. In this case,
the instrument stops all further measurements and the test
value with hold on the LCD. If the button HOLD is pressed
again, the hold value will be cancelled.
7. When the measurement is completed, the photo
detector cap has to be put on again and the power has to
be turned off.

5. Battery check and replacement
1. If in the left corner of the LCD display the symbol
Appears, it is necessary to replace one 9V battery.
2. After turning off the meter, the battery cover has to be
pressed and pushed at the same time in the direction of
the arrow to open it.
3. The battery has to be disconnected from the instrument
and replaced with a standard 9V transistor battery.
4. The battery cover has to be reinstalled.
6. Spectral sensitivity characteristics
7. Maintenance
1. The white plastic disc on the top of the detector should
be cleaned with a damp cloth from time to time and if
necessary.
2. The instrument may not be stored when temperature or
humidity is excessively high.
3. The reference level, as the 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, a
periodical calibration is recommended.
