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
min
to I
max
.
For the potentiometers, the following applies in general: Clockwise rotation means
an increase in the setting (longer ramp time or higher current).
