Adjustment / Reference
A 4.4.1 DARKCORR
DARKCORR ALL|CH<d><d>
Set the dark reference according to the current measurement.
A 4.4.2 DARKCORR_OFFSET
DARKCORR_OFFSET ALL|CH<d><d> [<float> <float> <float>]
Dark correction: Dark correction is a fixed offset for the three color channels. It should be reset every time the environ-
mental conditions (e.g. ambient light) change significantly. The factory-set standard value is based on a completely
insulated (dark) environment.
A 4.4.3 WHITECORR
WHITECORR ALL|CH<d><d>
Set the white factors according to the current light source.
A 4.4.4 WHITECORR_FACTOR
WHITECORR_FACTOR ALL|CH<d><d> [<float> <float> <float>]
White reference: During initial production, each channel of the controller is assigned a set of three factors. This value
allows for the correct calculation (regardless of the device) of color positions within the color spaces. The values depend
on the optical path (sensors, lenses, angles, distances, etc.). During production, a specific fiber is used to calculate
these values.
The white correction factor makes it possible to adapt the dynamic range to the current measuring situation. These
factors need to be determined again for this purpose. The dynamic range should be adjusted if the optical setup (e.g.
the fibers or the lighting situation) differs significantly from the factory/production environment. In order to reset the white
correction factor to factory settings, the value
1 1 1
needs to be set.
A 4.5
Measurement
A 4.5.1 AUTOGAIN
AUTOGAIN ALL|CH
This function determines a sensible combination of integration time and amplification in order to obtain the best possi-
ble range of values. The output of the STATUS command displays “AUTOGAIN” for as long as autogain is running. The
configuration of the controller should not be changed while the AUTOGAIN operation is being performed.
A 4.5.2 GAIN
GAIN ALL|CH<d><d> [<num>]
Set the hardware amplification level. There are 12 amplification stages from 0 to 11. The amplification stage is
2^<num>, i.e. the maximum amplification is 2048x.
