12.3.4 Brightness
This sensor task measures the mean brightness in a field of view and compares the result with the specified
switching points.
This feature check supports external Teach. The switching points are adjusted as an absolute to the current
measured value.
Select the shape of the field of view. A circle, a rectangle and a freely definable polygon, a circular
ring and a circular ring sector are available.
Adjust the field of view by holding the left mouse button depressed. You can rotate the rectangle by
correspondingly dragging the lever in the centre with your mouse.
The current result for brightness is shown as an average grey scale value or as a percentage. The
lightness value calculated during the teach process is 100%. The switching points designated
Min
and
Max
are adjusted on the right hand side. A graphic display is located in the middle, in which the
positions of the switching points are displayed and where they can be changed.
The right button is used to invert the result of the feature check.
