6400 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 cut off.
Setting: OFF
6402 ON-VALUE LOW FLOW
CUTOFF 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 cut off) 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%
