Qm Max set the upper range value for the mass flow.
Set the lower range value for the mass flow.
Set the upper range value for standard volume flow.
Set the lower range value for standard volume flow.
Select the damping for flow measurement.
The value set here relates to 1 τ (Tau). The value refers to the response time for a step flowrate change. It affects the
instantaneous value in the display and at the current output.
Default setting: 0.2 seconds
Set the switching threshold (0 to 10 %) for the low flow cut-off.
If the flow rate is below the switching threshold, there is no flow measurement. The setting of 0 % deactivates the low flow
cut-off.
Default setting: 1.0 %
Set the hysteresis (0 to 50 %) for the low flow cut-off as it is defined in the parameter 'Low Flow Cut Off'.
Default setting: 20 %
