General
The instrument has two operating modes:
EN
SEARCH and MAX.
The SEARCH mode is used to pinpoint
leaks.
The pitch of the acoustic signal indicates
the concentration of tracer gas around, or
in the ground above the cable. The pitch
rises as you approach the leak and falls as
you move away. Let the sound guide you
to the leak.

The MAX mode is used to compare the
gas concentration in a number of areas, e.g.
under manhole covers. This is useful to pre-
locate leaks after filling a whole length of
cable. This applies to pressure routes with
air pipes or cables that have no pressure
transducers or test valves.
N.B. Filling an entire cable from station to
end can take days if there is no air pipe.
