PPM GASURVEYOR 500 USER HANDBOOK
2
$
As the PPM Gasurveyor 500 has a wide variety of
available user selected options, it is not possible
to provide an operator handbook specific to each
possible variation, therefore, what we have pro-
vided in the following pages is the standard de-
fault of how the instrument would generally be
configured, with the possible options detailed in
italic text.
GMI recommend that you take the time to study your
instrument and, where practical and with advice from your
company’s Purchasing / Management departments,
highlight your particular instrument configuration.
The main features of the instrument are:
$
Rugged polypropylene case, sealed to IP54 rating
and suitable for outdoor use.
$
Two button operation allowing the user access to
all features.
$
LCD with backlighting which displays the current
gas readings (in both digital and analogue forms)
together with operational and status information.
$
Audible and Visual Geiger indication, configured
in PPM Flammable and Search ranges, provides
indication of gas concentration increase via the in-
creased rate of sounder and LED pulse.
$
Directly interfaces with the GMI Auto Test Cali-
bration Systems.
