
Tick here if you want to calculate the colour deviation, otherwise it will produce the current colour of
the field of view rather than the result (OK, NOK).
 The current result (in ΔE - distance between two colour coordinates in the CIELab colour coordinate
system) is displayed under Colour deviation. The switching point designated Max (max. 50) is
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.

Methods: Average value: The average value of all the pixels in the marked area is used.

Methods: Dominant single colour: The dominant colour in the spectrum in the marked field of view
is calculated and used. This means that any small errors such as dirt or reflections can be ignored.
Automatic brightness correction
In order to be independent of fluctuations in the ambient light, the device offers a means of automatically
correcting the brightness.
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.
