Setting 6 : Install dimming curve C2 or C3
Dimming curve C2 :
Indicates the linear relationship between the position of the slide control and the output power.
Dimming curve C3 :
More suited for stage lighting. The output power value and the control value (position of the
slide control) are directly proportional, yielding a more flexible control range in case of low
luminous intensity. This is why professionals prefer dimming curve C3.

Note that the factory setting is C3.
Our eyes are most sensitive to low luminous intensity, in particular to the range that lies below
25% of maximum luminous intensity (100%). Therefore, using C3 yields a more flexible control
range.
