Function description SYSTEM PARAMETER
POSITIVE ZERO RETURN Use this function to interrupt evaluation of measured variables. This is necessary when a
pipe is being cleaned, for example.
The setting acts on all functions and outputs of the measuring device.
If positive zero return is active, the notice message #601 “POS. ZERO- RET.” is
displayed.
Options:
OFF
ON (signal output is set to the value for zero flow).
Factory setting:
OFF
FLOW DAMPING Use this function to set the filter depth of the digital filter. This reduces the sensitivity of
the measuring signal to interference peaks (e.g. in the event of high solids content, gas
bubbles in the fluid, etc.). The measuring system reaction time increases with the filter
setting.
User input:
0...100 s
Factory setting:
1 s
