Pump Key Right Hand View Right hand view shows two gas inlets. The far inlet is for the gas sample for analysis. The near inlet is for the pressure measurement. Page 6 Geotechnical Instruments (UK) Ltd LFGASOM010 / Issue 1... -
Page 9: Switching The Analyser On And Off
3.3 Switching The Analyser On And Off When switching the analyser on a long beep will be emitted followed by the Geotechnical Instruments (UK) Ltd logo being displayed. The power on self-test will then commence. Following this the service reminder screen will be displayed. -
Page 10: Warning And Error Display
Note If any other types of warning or error are displayed it is advisable to contact Geotechnical Instruments (UK) Ltd for further information. Under and Over Range Codes If a reading is under range (ie below zero) it will be displayed with ‘less than’ chevrons (<<). This can occur if a channel has been incorrectly calibrated. -
Page 11: Storage
3.11 Event Log (Optional Upgrade) The GA2000 and GA2000Plus analysers incorporate the facility for a log of events. This can be used as an aid to monitoring the use of the analyser. It can also be used as a diagnostic tool if there is a problem with the analyser. -
Page 12: Calibration Record (Optional Upgrade)
GA2000/GA2000 Plus Gas Analyser 3.12 Calibration record (optional upgrade) The GA2000 and GA2000Plus have the facility to log user calibrations. This can be used as an aid to ensuring that gas measurements are valid and accurate. A ‘confirm calibration’ option will display in the calibration menu. When selected a further sub-menu is displayed which allows the user to select which gas to confirm. -
Page 13: Memory
GA2000 / GA2000Plus Gas Analyser 3.14 Memory The analyser's memory is volatile, although it is retained by a battery back-up system. The memory is not to be used as a permanent storage medium and any data should be transferred to a more permanent storage medium as soon as possible. -
Page 14: Print Data
Allows all the data currently stored to be printed. This may only be carried out with an appropriate RS232 cable (available from Geotechnical Instruments (UK) Ltd) and a printer with a serial port connection, or a PC based ‘Terminal’ programme. -
Page 15: Taking Readings
GA2000 / GA2000Plus Gas Analyser Taking Readings Inhaling hydrogen sulphide gas can cause death. It is the responsibility of the user Warning to ensure that he/she is adequately trained in the safety aspects of using H S. In particular, where hazardous gases are being used the gas exhausted from the analyser must be piped to an area where it is safe to discharge the gas. - Page 16 If the ID has the “record borehole flow” flag selected, the analyser will now give you the option of measuring the flow from the borehole. The GA2000 and GA2000Plus have the capability to measure the gas flow from a borehole without the need for an additional flow pod. Connect the sample tube from the borehole to the flow inlet port on the analyser (the lower of the two QRC connectors).

Page 18: Temperature Probe Reading
GA2000/GA2000 Plus Gas Analyser 4.5 Temperature Probe Reading The GA2000 and GA2000Plus have the facility to automatically display and record the borehole temperature via an optional temperature probe. When a temperature probe is fitted to external port 1 (RS232 port), the temperature will be displayed in the ‘Read Gas Levels’... -
Page 19: Modem Operation
‘purged’. CO measurement For a GA2000Plus the CO measurement is compensated for hydrogen cross sensitivity up to a concentration of 1% hydrogen. If a hydrogen concentration above 1% is present, the CO reading will become inaccurate. - Page 20 If it is a GSM type then a suitable signal strength must be present. Switch the analyser and modem on. Page 18 Geotechnical Instruments (UK) Ltd LFGASOM010 / Issue 1...

Page 21: Calibration
If this calibration is completed incorrectly it may decrease the accuracy of the Gas Analyser. and O can be measured by all GA 2000 and GA2000Plus analysers as standard; these channels can be user calibrated. The analysers have other gas channel options that are specified at manufacture;... -
Page 22: Calibration Gases
To improve higher levels use gas mixture 3. • For standard CO only 100ppm CO gas is needed. • For CO (H compensated) (GA2000Plus only) both CO 100ppm and H 1000ppm gases are needed. Calibration gas Mixture 1 Mixture 2... -
