Taking gas and flow measurement
The top methods of taking a reading
There are two methods to taking a reading, simple gas and a detailed reading, please below for explanations of
both:
Simple gas: Just takes a gas reading and nothing else, this mode can be accessed via the special actions.
Detailed reading: This mode takes you through various steps to achieve (system and barometric) pressure,
gas readings and flow (if required).
Detailed reading explained
With a detailed reading everything is operated of the right soft key, the process will be slightly different
depending on whether you have user prompts enabled but either way it is the same process.
Selecting ID (if required) > Air purge/Baro reading > Relative pressure reading > Gas reading > Flow (if required) >
Answering ID questions (if required) > Store.
A full detailed flow chart of the process can be found on the next page.
