Switching point adjustment (KAL-AK)
The potentiometer is now used to set the switching point (threshold) of the flow
switch. The switching point is displayed as a blinking LED. If the flow rate
increases to the point that illuminated LEDs (actual flow value) reaches the
position of the blinking LED (set point), the flow monitor switches over from
ALARM to FLOW. This can be seen at the display: the bi-coloured LED that was
showing a steady red light now switches to a steady green light. The output is
also switched at the same time.
