10.6.4 Frequency output
The FM100 flowmeter provides a scalable frequency output. When this output is
activated, the measurement variable (flow or temperature) associated with the
frequency output is output proportionally as a frequency with a 1: 1 pulse / pause
duration. The output frequency at the end of the measuring range can be set
(parameter "maximum frequency"). With the two parameters "Value for 0 Hz" and
"Value for max Hz", the frequency output in the measuring range can be freely
scaled.
Behavior on OVERFLOW:
If the measured value is in the overflow range, a constant frequency is output.

10.6.5 Control input
Output 1 can be configured as a control input. This can reset the MIN / MAX
memory or the partial quantity counter depending on the assigned measurement
variable.
