Operation
Performing White Balance
We recommend performing a white balance after replacing a sensor (fiber optics) or if the measurement
environment has changed.

During white balancing: A dynamic field in the web interface provides information on the current progress.
The result of the correction process is stored directly in the controller and does not have to be saved sepa-
rately in a setup. If the white balancing process fails, the previous white balance continues to be used.

You should perform an automatic modulation before white balancing and then wait approx. 45 min.
before starting the white balance.
This improves the stability of the measurement accuracy over the long term.
Do not change the light source brightness of the LED after white balancing. Repeat the white balancing
process after changing the light source or the sensor arrangement and after sensor replacement.
The white balance can also be used to spread the signal thus improving the difference between light
and dark. In this case the lightest color to be detected is defined as white (L = 100, a = 0, b = 0).
