Portable oxygen analyser analox Mini O2DII

Operation
16.4.1
The analox Mini O2DII is supplied with a single DII adapter that enables the analyser to be
connected directly to the outlet of the nitrox tank.
16.4.2
Make sure that the sensor seal has been removed. Connect the DII adapter to the analyser
pushing the adapter onto the turret of the sensor. The O-ring on the sensor makes fastening
easy.
16.4.3
Hold the DII adapter, turned towards you, firmly against the cylinder outlet. Slowly open the
cylinder valve until gas can be heard hissing through the flow adapter.
WARNING
Open the cylinder valve
VERY CAREFULLY
16.4.4
Close the cylinder valve after fifteen seconds when the Mini O2DII shows a stabilised reading.
If in doubt, carefully repeat the process and make sure the flow of gas is gentle.
16.4.5
A couple of seconds after the gas flow has stopped, the reading will begin to change to the
surrounding level of air of 20.9% O2, the reading should therefore be taken when the gas flow
is open.
WARNING
Do not pressurise the sensor as the readings will be inexact.
