1. Instruction
This digital light meter is a precision instrument used to measure illuminance in the
working area. It is totally cosine corrected for the angular incidence of light.
The light meter is compact, tough and easy to handle due to its construction. The
light sensitive component used in the meter is a very stable, long life silicone diode.
2. Features
•Light-measuring levels ranging from 0.1Lux to 200.000 Lux, or in FC from 0 to
20.000 FC (foot candle)
•High accuracy and rapid response
•Peak-Hold function for capturing peak values
•Unit and numeral display for easy reading
•Automatic zeroing
•The Correction factor doesn’t have to be manually calculated for non-standard
light sources
•Short rise and fall times
•Suitable for LED light
3. Specifications

2. Power key: the power key turns the light meter ON or OFF.
SP_200K-BA-e-1811 5
3. HOLD button: With the HOLD key you can freeze the actual measurement
value. The device does not show any other measurement values, unless the
HOLD button is pressed again.
4. Range button: the range button has to be pressed to change the ranges of
200Lux/20FC; 2.000Lux/200FC; 20.000Lux/2.000FC; 200.000Lux/ 20.000FC
circularly.
5. Lux/FC Unit button: This key has to be pressed to change between the Lux or
FC unit.
6. Photo detector
7. Cover of the photo sensor. It serves to protect the sensor if you don’t use the
light meter.
5. Spectral sensitivity characteristics
Concerning the detector, the applied photo diode with filters makes the spectral sen-
sitivity characteristic almost meeting the standard C.I.E. (International Commission
on Illumination) photopic curve V ( ) as described in the following chart below:
6. Operation instructions
1. Power-key: The power key has to be pressed to turn the light meter ON or
OFF.
2. Selection of the Lux/FC scale: The range selection switch has to be set to
the desired Lux/FC range.
3. The photo detector cap has to be removed and it has to be faced to the light
source in a horizontal position.
4. The illuminance nominal value can now be read from the LCD display.
5. Over range: If the instrument only displays one “1” in the M.S.D., the input
signal has been too strong and a higher range should be selected.
6. Data-HOLD mode: The HOLD key has to be pressed to select the HOLD
mode, the light meter will stop all further measurements. If the HOLD button is
pressed again, this operation will be cancelled and the light meter will return to
normal operation.
7. When the measurement is completed, the photo detector cap has to be
clipped on again and the power key has to be turned off.
8. Turn the device off

7. Battery check and replacement
1. As the battery power is not sufficient, the LCD will display the symbol
and replacement of a new battery type 9V is required.
2. Therefore, the instrument has to be powered off. Then the battery cover has to
be pressed and pushed (at the same time) in the direction of the arrow shows
to open.
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 snapped on again.
8. 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 exces-
sively high.
3. 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.

“0.00” on a continuous basis; if this is the case, do not manipulate the potenti-
ometer at the back of the housing.
