Baumer VeriSens ID Series Technical Documentation Manual page 201

In order to be independent of fluctuations in the ambient light, the device offers a means of automatically
correcting the brightness.
The mean brightness in the field of view of the reference area should exceed a grey scale value of 128 to
ensure reliable operation.

Use current field of view: The current defined field of view is used as a reference. It should only be
used if the pattern being checked is very similar.

Use, do not carry reference area: Here, a field of view is defined as a reference area, for example
by attaching a white label to the edge of the conveyor belt (static). The brightness correction is now
guided by the brightness of this area.

Use, carry reference area: This function is only available in connection with part location. A field of
view is still used as the reference area. However, this is carried with the position correction. The
brightness correction is now guided by the brightness of this carried area.

Confirm your settings and return to the feature list with OK. Return to the feature list without making
any changes with Cancel.
