What is a characteristic adjustment?
The characteristic adjustment enables the adaption of the dimming
characteristic of the lamps (ballasts) to the sensitivity of the eyes.
On the one hand with the characteristic adjustment the curve of the
ballasts can be changed to suit requirements, on the other hand with
constant lighting control a second lighting strip (slave) can be
increased or reduced by a predetermined brightness value in
dependence on a master output. In this case the brighter lighting strip
should be selected as the master, i.e. the slave output is controlled
as darker by the characteristic adjustment.

Number of value pairs
Options: 2/3/4
This parameter defines the number of value pairs which are used in
the characteristic curve. The characteristic correction (curve) results from
a maximum of four value pairs. Between the value pairs a linear interpolated
curve (straight) is used.
Accordingly, additional parameters appear with which the individual X/Y
values are to be entered to suit the parameterised number of value pairs.
