Operation
colorSENSOR CFO
Since a combination of control parameters such as amplification, averaging, receive brightness and LED
brightness is taken during automatic modulation, one needs a control variable. This is the measurement
frequency at which the data is to be output via the digital I/Os.
Automatic modu-
lation Effective measurement
frequency (Hz)
Value 1
Starts automatic modulation of the controller.
Depending on the measurement frequency, a
maximum of 200 values are averaged. You can
define the minimum measurement frequency. The
measurement frequency can be between 0.01 and
10,000 Hz for the CFO100 and 30,000 Hz for the
CFO200.
LED

The internal LED and ambient light compensation
can be switched off or on for testing self-luminous
objects.

Click on
Run automatic modulation
to modulate the system.
i
The measurement frequency indicates only the minimum output update. If the set measurement fre-
quency is less than 1000 Hz, the digital outputs are still updated to a minimum of 1000 Hz.
i
i During automatic modulation, the lightest color to be detected should be placed under the sensor.
