Quickstick Oxygen Analyzer Operation Manual
4. Operation
4.1. Open the cylinder valve slowly until a slight hiss can be heard.
4.2. Hold the sensor end of O
2
Quickstick
(the end without the lanyard) against the valve opening so that
the Nitrox mixture passes over the oxygen sensor. Be careful not to block the exhaust ports on the
side.
4.3. The reading should stabilize in 15 seconds or less and the display reading taken.
4.4. If you cannot obtain a stable reading, check that you still have a very gentle flow of gas and repeat. If
you still cannot obtain a stable reading see Troubleshooting section or use another analyzer.
4.5. 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% O
2
.
Never expose the Oxygen Sensor to pressures other than ambient or you may cause damage and/or
false readings. Damaged Sensors will not provide accurate gas analysis. Inaccurate gas analysis can
lead to serious personal injury or death when the gas mixture that was analyzed is used for breathing.
Gas, even under moderate pressures, can cause extreme bodily harm. Never allow any gas stream to
be directed at any part of your body.
5. Maintenance
5.1. During the first 12 months of the warranty period, the O
2
Quickstick
should be returned to the
dealer/manufacturer for repair. Your O
2
Quickstick
should give you three years continuous operation
with proper care before needing sensor replacement.
5.2. To clean the O
2
Quickstick
use a damp soft cloth.
5.3. Although designed to be water-resistant the O
2
Quickstick
should not be intentionally immersed in
liquid or left outside unprotected.
5.4. The O
2
Quickstick
is built to resist the effects of day to day shocks and drops but remember it is a
precision oxygen analyzer and should be looked after carefully to give long trouble free service.
5.5. Protect the O
2
Quickstick
from long periods of direct sunlight and do not subject it to high or low
temperature extremes.
5.6. Battery Replacement – To replace the battery, gently push and remove the end cover with thumb (the
side with the lanyard). See figures 1 & 2. Gently pull the battery out from the O
2
Quickstick
housing.
Replace with new battery and reassemble.
Be careful not to pull to hard as you can separate
the wires from the end cap and damage the Quickstick.
Should you separate the wires from the end cap return
the Quickstick to Nuvair for repair,
DO NOT ATTEMPT THIS REPAIR ON YOUR OWN.
Be sure to dispose of spent, leaking, or damaged Batteries properly, according to local
regulations.
