Functional description SYSTEM PARAMETER
POSITIVE ZERO
Use this function to interrupt evaluation of measured variables.
RETURN
This is necessary when a piping system is being cleaned, for example.
This setting acts on all function and outputs of the measuring device.
Options:
OFF
ON → Signal output is set to the "ZERO FLOW" value.
Factory setting:
OFF
FLOW
Use this function to set the filter depth of the digital filter.
DAMPING
The sensitivity of the measurement signal can be reduced with respect to interference
peaks (e.g. in the event of a high solid content, gas bubbles in the fluid etc.).
The reaction time of the measuring system increases with the filter setting.
User input:
0 to 60 s
Factory setting:
2 s
!
• The system damping acts on all functions and outputs of the measuring device.
• The higher the value set, the stronger the damping (higher response time).
