colorSENSOR CFO
i
The measuring frequency indicates only the minimum output update. If the set measuring frequency is
less than 1000 Hz, the digital outputs are still updated to a minimum of 1000 Hz.
i
During automatic level adjustment, the lightest color to be detected should be positioned beneath the
sensor.
Performing White Balance
A white balance is required after replacing the sensor (optical fiber) or when the measuring environment has
changed.

Recognition Profile.
Recommendation: Position the white standard (optional accessory) at the permissible measuring dis-
tance to the sensor.
Click on the Set button, see Fig. 26 .
During white balancing process:
A dynamic field on the web interface provides information on the current progress.
The results of the correction process are not saved directly in the controller; it is necessary to save them
separately in a setup process. If the white balancing process fails, the previous white balance continues to be
used.
i
Do not change the light source brightness of the LED following white balancing. Repeat the white bal-
ancing process after changing the light source.
i
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).
