4.6 Automatic Switching Threshold Adaption
4.6.1 Description
Cleaning cycles can be extended with the help of
automatic switching threshold adaptation. The relative
sensor measurement value is continuously and
automatically adapted in proportion to the detected soiling
of the front lens or transmitter. This function can be
especially helpful when detecting highly transparent
objects to make the detection more stable with respect to
soiling and to keep it stable for a longer time.
