8.11 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:
o Simple gas: Just takes a gas reading and nothing else, this mode can be accessed via the
special actions
o Detailed reading: This mode takes you through various steps to achieve (relative and
barometric) pressure, gas readings, flow (if required) and fill in any questions you may have
assigned to your ID (GAM 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.
