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.
