Table 20: Calibration of brightness value
The individual parameters are described in more detail below:
Correction Lux value
With the correction of the lux value, the measured lux value is shifted by an adjustable
percentage offset. Thus, at a set value of -50%, the measured value is reduced by 50%. Thus
the presence detector would output the value 200 at a measured value of 400 lux and a
correction value of -50%.
