Gem Analyzer In Gas Analyzer (Ga) Mode; Simple Gas (Special Action) - LANDTEC GEM5000 Operating Manual

GEM5000 gas analyzer

8.4 GEM analyzer in Gas Analyzer (GA) mode

The operator may toggle between GEM (a gas extraction monitor) and GA (a landfill gas
analyzer) mode of operation if required. From the 'Special Action' menu, select the
middle soft-key to toggle between GEM and GA Mode.
Note: The GEM5000 differs from the GEM2000 series of analyzers in that all IDs
and Memory within the instrument are contained in a single area. They are
not specific to GEM or to GA mode. GEM and GA mode should be
considered as "modes of workflow" rather than instrument modes.
Readings can be taken in either workflow mode GEM or GA.
LSGAM now supports a new flow device called "NO FLOW" for
probes. If "NO FLOW" is selected during ID Setup, the instrument
will default to the GA workflow after a Device ID containing
"NO FLOW" is selected. Subsequent selection of an ID without
"NO FLOW" for the flow device will cause the instrument to return
to the GEM workflow.

8.5 Simple GAS (special action)

A simple gas reading is similar to that of a GA mode reading except that it does not record
temperature nor does it record relative pressure. This is useful if strictly a gas composition is desired.
There are two ways to start a simple gas reading. The First is to press 'special action' followed by simple
gas (1) before pressing 'start' to begin a reading. The other is to simply press the pump key before
pressing the 'start' button on the reading screen. Once the Simple Gas reading is activated the Start
button will become a store button.
