1.1 Indications for Use
The AII- 30 00 Seri es Oxygen Analyzers are int en de d to measur e and dis play the
concentration of oxygen in compressed breathing air tanks intended for scuba
diving, for personnel safety, area monitoring, O2 deficiency in confined spaces,
check ing b reathing air tanks and confirming the O2 levels prior to welding.
Users m ust read th e followi ng statements as they ar e essential to reducing the r is k of us e erro r du e to ergo nomi c feat ur es of t he devi ce o r
the environment in which the device is intended to be used.
The devices have been designed and manufactured in such a way that when
used under the conditions and for the purposes intended, they will not compromise the clinical co ndition or t he safety of patients, or safety of the users or
other persons.
Conform ity wi th ess enti al re quir eme nts has been demo nstr ate d by ver if ying th e
perform ance of the device under normal co nditio ns, be nch testi ng and determining that undesirable malfunctions constitute minimal risk to users.
Do not sterilize, autoclave, liquid sterilize, immerse in any liquid or expose the
device or accessories t o st eam, ethylene oxide or radiat ion s t er ilization.
The devic e is inten ded to be re-usabl e. Shoul d the de vice or acc ess ories com e

1.2 Intended Use
The AII-3000 Series Oxyge n Analyzers are intended to meas ure and display
the concentration of ox ygen in compressed bre athing air tanks intended for
scuba divi ng, for perso nnel saf ety, ar ea moni toring , O2 defi cienc y in conf ined
spaces, checking breathing air tanks and confirming the O2 levels prior to
welding.
1.3 Device Description
The AII-3000 S eries Oxygen Analyzers can be positioned on a table top or
pole (tri po d wi r e sta nd and V-m o u nt dovetai l attachments ar e m ounted o n t h e
back of the device) and are readily portable from one location to another.
They pro vi de con ti nuous , f ast, rel iabl e a nd ac cur at e oxyg en me asur eme nts of
up to respiratory care systems.
The devices utilize an electrochemical galvanic fuel cell type oxygen sensor of
the type t hat is exte nsivel y used to meas ure o xygen co nce ntratio ns f rom 0%
to 100% in gas streams. O xygen, the fuel f or this electroch emical tr ansducer,
diffus ing into th e sensor thr ough a g as permeabl e membra ne reacts ch emically at the sensi ng electro de to produ ce an elect rical curr ent o utput propo rtional to the ox yg en con ce ntra tio n in the g as p has e. T he s enso r h as an absolute zero meaning that when no oxygen is present to be chemically reacted
the LCD displays 00.0 oxygen.
The sensor’s signal output is linear over the entire range, remains virtually
constant over t he specif ied us eful li fe and dro ps off sharply at the e nd. The
sensor itself requires no maintenance and is simply replaced at the end of its
useful l ife like a ba ttery. In asmuch as t he sensor i s a transdu cer in its own
right, its expected life is not affected by whether the analyzer is ON or OFF.
A batter y pow ered st ate-of -the-ar t mi cro-pro cesso r con verts t he s ensor’ s signal output repr esentin g the partial pr es s ure of ox ygen in t he gas s tream b ei n g
analyzed. The resulting oxygen reading is displayed by a large easy to read
backlit liquid crystal display (LCD) that has a resolution of 0.1% oxygen. The
microprocessor is controlled from a keypad and provides features like system
diagnostics, warning indicators, controls and an alarm capability for continuous monitoring that enhance both safety and effectiveness.
Prior to shipment, every device is thoroughly tested at the factory and documented in the form of a Quality Control Certification that is included in the
Instructions for Use su pplied with ever y device.

4.2 Install Batteries
All devices are powered by two 1.5V AA alkaline batteries which must be installed before the device can be operated.
The battery compartment is located at the rear of all devices. Initially
this proc edure c an be som ewhat dif ficult. C are sho uld be take n not to
damage the case when removing the battery compartment cover.
4.2.1 Procedure:
1. Remove the device and the (2) AA 1.5V Alkaline batteries from the foam
shipping container.
2. Turn t he devi ce over so the shortest raised line on the batt ery co mpartment cover is pointing away from you.
3. Lift the tripod wire stand up and away from the case.
4. Grasp the c ase wit h both hands, use y our thum bs pres s dow n firm ly on
the raised lines and push the battery compartment cover away from you.
5. Locate the positive (+) and negative (-) terminals on the battery.
6. Assure the battery contacts are clean.
7. Ali gn one batt ery’s posi tive (+) termin al with t he corr espondin g (+) battery sy mbo l m o lded into the cas e.
8. Insert the battery into the compartment.
9. Repeat with the remaining battery.
10. Replace the battery compartm ent cover, make sure it snaps into p osition
and is secured flush against the case. Replace the wire stand as required.
Replac e the bat teri es w ithi n t we nty- four (24) ho ur s of th e batt ery sym bol appearing on LCD display because batteries decline at different
rates. Calibrate the device afte r rep lacing the bat te r ies.

4.3 Install Oxygen Sensor
The device cannot function until the oxygen sensor is installed. Once installed,
allow the sensor to stabilize for 15-20 minutes in ambient air before attempting to calibr ate the device.
NEVER - Attempt to open, repair or service the oxygen sensor.
Refer to Sect ion 3 f or hi nts an d warni ngs co ncer nin g th e han dli ng an d
environmental considerations of the oxygen sensor and the device.
4.3.1 AII-3000 A/M:
1. Remov e the contents from the shipping conta iner as shown in section 4.1
and check for damage .
2. The coiled cable uses a common RJ11 phone jack at both ends, making a
bad connection impossible.
3. Inst all the sensor awa y from any humidifyin g device to pr event moi sture
from condensing on the sensing surface and assure accurate calibration
and oxygen readings.
4. Connect one end of the cable to the device in the same manner you
would co nnect a t elephon e. Simply f i n d and re gi s t er the male pl ug at the
end of the coiled cable and insert it into the mating female jack on the
side of the device.
5. Connect the other end of the cable to the sensor in the same manner.
6. For diffusion sampling of static, ambient or controlled atmospheres –
simply expose the oxygen sensor to the atmosphere to be sampled.
7. For sampling breathing circuits with flowing gas, position the sensor
vertically for optimum results. Avoid letting the gas stagnate and facilitates the flow of g as across t he sensing ar ea of t he sensor to produ ce a
more accurate measurement of the gas stream to be measured.
8. Install the tee-adap ter in the breathing circuit.
9. Screw the flow diverter to the sensor.
10. Ensure the o-ring is lightly lubricated for ease of entry and a tight seal
between the flow diverter and tee adapter.
11. Insert the assembled flow diverter/sensor into the tee allowing air or
100% oxygen (dry, no n-humidif ied) to f low p ast t he se nsor at a r at e l ess
than 10 liters per minute.
4.3.2 AII-3000 AHC/ MHC:
When the HC (hose connection) version is ordered, the device is shipped with
the sensor installed.
