GENERAL DESCRIPTION
The AGP 45 exploits the latest in sensor and
electronics technology to offer a compact and
affordable gas leak detector. Primarily designed to
detect the high methane content of natural gas it is
also sensitive to a wide range of combustible gases.
INSTRUMENT OPERATION
1. Press and hold
UP
button for 0.5s to turn on.
It is recommended to turn on the unit in
uncontaminated air i.e. away from the area where a
leak is suspected.
2. The green LED will illuminate to indicate the
instrument is powered on. During the instrument
warm-up period of around 30s, the Red LED may
flicker and buzzer may sound. After the warm-up
period the buzzer will sound every few seconds to
indicate the instrument is operational.
3. The sensitivity of the instrument can be tuned by
pressing the
UP
button to increase the sensitivity or
by pressing the
