5.2 DII Flow Adaptor
5.21 The Analox O2 Portable comes complete with the unique DII
adaptor which allows to you to directly apply the analyser to the
outlet on your nitrox tank.
5.22 Connect the DII adaptor to the analyser by pushing the adaptor
over the sensor turret. The O ring on the sensor should ensure a
comfortable fit.
5.23 Hold the DII adaptor firmly against the cylinder outlet facing
you. Very slowly open the pillar valve until gas can just be
heard hissing through the flow adaptor.
WARNING
Open cylinder valve
EXTREMELY CAREFULLY
5.24 Close the pillar valve after fifteen seconds when a stable
reading is observed on the O2 Portable.
If in doubt repeat the procedure taking care to ensure a very low
gas flow.
5.25 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.
