Carrying out Measurements
Before commissioning, please observe the instructions concerning the Prescribed Use as
well as the Safety Instructions and the Technical Data.
| Turn the ON/OFF switch (2) to ON.
|
Remove the protective cap from the light sensor and hold it horizontally ensuring that the light
hits
|
the light sensor vertically. Avoid shadows of your own body in direction of the sensor.
|
Read the value (1) indicated on the display. In the measuring range 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 100000 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 meas-
uring range (3) to determine the correct 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.
