The brightness of LEDs I1 and I2 depends on the strength of the output current
and thus serves a rough visual control.
The ramps control the time required by the output current to reach a new
value. The control range is between 100 ms and 10 s at maximum change from
I to I .
min max
For the potentiometers, the following applies in general: Clockwise rotation means
an increase in the setting (longer ramp time or higher current).
