4.7 Calibration of brightness value

The following figure shows the individual cell options for calibrating the 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%.

Reflectance of the
environment:
Indicates how much of the
light is reflected back
(1=100%, 0 = 0%)
Adjustment value for external

Defines whether the presence
detector should hold the
teach-in values after the
download or load the factory
settings.
