Base flow.
Base flow can be switched on and off here. Base flow is a con-
stant flow that must not be included in the calculation. If this function is select-
ed, an appropriate icon appears on the display (
7.6 Numerical display
).
8
Change.
With the associated button you can access edit mode in order to
change the relevant measurement parameter.
9
Delay.
Delay prevents an individual spot from causing a trigger event. If a
trigger value is undershot or exceeded again within the delay time, the trig-
ger is regarded as invalid and there is a further wait for an effective trigger. In
high-frequency ventilation the delay is set down by default.

Ext. trigger
).
2
Start.
You can determine whether volume measurement is to take place with
a rising or falling signal edge.
3
Reset.
By pressing the assigned reset button the default values are loaded
for the flow trigger. Volume measurement is possible in most cases with these
settings.
4
Base flow.
Here you can specify base flow. Base flow is a constant flow that
must not be included in the calculation. If this function is selected, an appro-
priate icon appears on the display (
6.6 Numerical display
