15.0 Glossary of terms
The 5000 series refers to the GA5000, GEM5000
and the Biogas5000 gas analyzers.
A flow device used to aid accurate flow
measurement.
Operational errors are prefixed on the analyzer
by the word ERROR followed by an error code.
Refer to the list of standard error codes for
more information.
Analyzer warnings are prefixed by the word
WARNING followed by a relevant description.
There are two types of warning messages
displayed; general warnings that may not
necessarily affect the instrument’s function (for
example, battery power low) and operational
parameters that could affect the performance of
the analyser (for example, CH
4
out of
calibration).
Device for measuring velocity of gas in the pipe.
The GEM5000 analyzer can be set to convert
into a flow. See also flow measurement.
The GEM5000 is ATEX certified to zone 1 & 2
areas above ground not in mines.
This refers to the channels where external
devices will be connected or displayed.
The analyser has a built-in backlight for low
ambient light conditions. This can be toggled
on/off using the backlight key.
The atmospheric pressure at the given location.
Typical location from which a gas sample is
obtained.
The gas analyzer is carefully calibrated against
known standards.
The GEM5000 instrument has the facility to log
user calibrations as a validation tool.
A method of gas detection that works on the
basis of a chemical reaction with the target gas.
Process used to clear out gas from the sample
tube and analyser prior to taking a new reading.
