Inhaling hydrogen sulphide gas (H2S) or other harmful gases can cause death. It is the responsibility
of the user to ensure that he/she is adequately trained in the safety aspects of using H2S and other
harmful gases. 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. Hazardous gas can also be
expelled from the instrument when purging with clean air.
Good practice
Travel to site with the gas analyser in the vehicle's interior - not in the boot, where it may be subjected to
extremes of temperature and possible shock damage. Do not place the gas analyser against anything hot
(e.g. gas extraction pipe, car body or in an unattended car during the summer) as this will cause a
temperature increase in the gas analyser and may cause erroneous readings.
When moving around a site, protect the gas analyser from strong direct sunlight and heavy rain.
Always use the water trap! If the water trap becomes flooded, change the filter and ensure all tubes are
clear of moisture before re-use.
Note: If the exhaust of a 5000 series gas analyser is connected to a pressurised system then this results in a
flow of gas out of the inlet flow port.
Creating an ID
There are two different methods to creating an ID, either via Gas Analyser Manager or via the instrument.
If created on the analyer, you can only fill out basic information, such as ID code, description and ID type.
Whereas on GAM, you can assign site and ID questions (please see below), assign flow devices, input GPS
coordiantes etc.
To create an ID on GAM please consult the GAM operating manual. To create an ID on the instrument:
1) Press the left soft-key for ‘Next ID’
2) Press the right soft-key for ‘Add’
3) Input an ID code using the keypad
4) Press enter
5) Using the corresponding number to input different properties of the ID
6) Once you are happy, press the middle soft-key for ‘add’
