5.0 Operation
5.1 Standard O2 Flow Adaptor
5.11 Connect the standard flow adaptor to the sensor and pass the gas
to be analysed over the sensor slowly at 1 to 2 litres per minute
until the reading stabilizes. There should be no significant rapid
change in reading when the gas flow is stopped as this indicates
that the flow was too high and the sensor pressurized. If a rapid
change is seen within 2 or 3 seconds of the gas being turned off,
repeat at a lower flow.
5.12 When a stable reading is observed with the gas flow on and 2 to
3 seconds after being turned off, take the reading.
5.13 Note that after a few seconds of the gas flow being stopped the
reading will begin to change towards the level in the surrounding
air of 20.9% O2 you should therefore take the reading while
flow is on.
WARNING!
Do not pressurise the sensor as inaccurate readings will result.
