Gas Measurement Process
(G210 - Best Practice)
When the instrument is first switched on it should be purged with fresh air and allowed to
stabilise for a few minutes.
Make sure that you have carried out all the preliminary checks as listed in section '6.1
Preliminary Checks – Best Practice' and that the instrument is ready to take the first reading.
Always use a regulator pressure kit with the G210 instrument.
Note: Alternative methods of pressure reduction are available and could be used. However, to
avoid irreversible damage to the instrument, please seek guidance from the supplier/manufacturer
before using any other pressure device.
