3.1.3 L.F. CUTOFF : Low Flow Cutoff
To avoid erroneous measurements at low flow rates the Low
Flow Cutoff can be used ( see Fig. D.2).
Fig. D.2 : Low flow cutoff
If the flow rate drops below the "Cutoff On" level all outputs
will be switched off and if the flow rate exceeds the"Cutoff
Off" level the outputs will be activated again.
The "Cutoff On" level must be lower than the "Cutoff Off"
level otherwise a PARAMERROR message appears at the
parameter check (see section D.6).
After entering the function either YES or NO can be selected.
If YES is selected functions 3.1.4 and 3.1.5 become active.
If NO is chosen the low flow cutoff becomes inactive and
functions 3.1.4 and 3.1.5 will not appear on the display.
