Carrying out Measurements
Before commissioning, please observe the instruc-
tions concerning the Prescribed Use as well as the
Safety Instructions and the Technical Data.
- Turn the On/Off switch (5) to the desired measuring range.
- Remove the protective cap from the light sensor and hold it hori-
zontally ensuring that the light hits the light sensor vertically.
Avoid shadows of your own body in direction of the sensor.
- Read the value (2) indicated on the display. In the measuring
ranges of 200 and 2000 lux, the indicated value corresponds to
the intensity of light in lux. In the measuring range of 20000 lux,
you have to multiply the indicated value on the display by 10; in
the measuring range of 50000 lux, you have to multiply it by 100
to determine the correct light intensity.
- In case of overflow indication ( "1" is indicated on the display),
please switch to the next measuring range to determine the cor-
rect light intensity.
- After the measuring process, please switch off the device (On/Off
switch to "OFF") and put the protective cap back onto the sensor.
Replacing the Batteries
The device is already equipped with a built-in 12V alkaline battery
of the type A23 when being delivered. As soon as the Low-Bat indi-
cation (1) appears on the display, please replace the battery
because otherwise, the precision of the indication is no longer guar-
anteed. To replace the battery, proceed as follows.
