Shut off the line under test as
much as possible with the
valves and fittings available.
The zone under test is limited
to the line through which the
carried gas flows to the
detector.
It is therefore necessary to
prevent the flow of carrier
gas through the lines not
under test, using the valves
V1, V2, and V3.
