16.0 Glossary of terms
The 5000 series refers to the GA5000, GA5000
and the Biogas5000 gas analysers.
Operational errors are prefixed on the analyser
by the word ERROR followed by an error code.
Refer to the list of standard error codes for
more information.
Analyser 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 GA5000 analyser can be set to
convert into a flow. See also flow
measurement.
The GA5000 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 analyser is carefully calibrated against
known standards.
The GA5000 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.
The CIRIA guideline ‘Assessing the risks posed
by hazardous ground gases to buildings’
proposes that gas concentrations and flow
rates should be monitored.
Process used to clear out gas from the sample
