Note!
Quick Setup automatically deactivates the function EMPTY PIPE DETECTION (6420) so that the
device can measure flow at low gas pressures.

ASSIGN LOW FLOW CUTOFF
On account of the low mass flow involved when gas
flows are measured, it is advisable not use a low flow
cutoff.
Setting: OFF

ON-VALUE LOW FLOW CUT OFF
If the ASSIGNMENT LOW FLOW CUTOFF function
was not set to "OFF", the following applies:
Setting:
0.0000 [unit]
User input:
Flow rates for gas measurements are low, so the
value for the switch-on point (= low flow cutoff)
must be correspondingly low.
6403
OFF-VALUE LOW FLOW CUTOFF
If the ASSIGNMENT LOW FLOW CUTOFF function
was not set to "OFF", the following applies:
Setting:
50%
User input:
Enter the switch-off point as a positive hysteresis in
%, referenced to the switch-on point.
