1 Introduction

Congratulations on your purchase, these Instructions for Use describe the pre­cautions, set-up, operation, maintenance and specifications of the AII-3000
Series Oxygen Analyzers.

This symbol means CAUTION – Failure to read and comply with the
Instructions for Use could damage the device and possibly jeopardize
the well being of the user.

Note: Advanced Instruments Inc. cannot warrant any damage resulting from
the misuse, unauthorized repair or improper maintenance of the device.

1.1 Indications for Use

The AII-3000 Series Oxygen Analyzers are intended to measure and display the
concentration of oxygen in compressed breathing air tanks intended for scuba
diving, for personnel safety, area monitoring, O2 deficiency in confined spaces,
checking breathing air tanks and confirming the O2 levels prior to welding.

Users must read the following statements as they are essential to re­ducing the risk of use error due to ergonomic features of the device or
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 condition or the safety of patients, or safety of the users or
other persons.

Conformity with essential requirements has been demonstrated by verifying the
performance of the device under normal conditions, bench testing and deter-

mining that undesirable malfunctions constitute minimal risk to users.

Do not sterilize, autoclave, liquid sterilize, immerse in any liquid or expose the
device or accessories to steam, ethylene oxide or radiation sterilization.

The device is intended to be re-usable. Should the device or accessories come
in contact with patient bodily fluids, either dispose of the device or clean with a
soft cloth dampened with 70% isopropyl alcohol solution in water and allow the
components to air-dry before re-use .

Do not operate the analyzer near equipment capable of emitting high levels of
electromagnetic radiation as the reading may become unstable.

In order to obtain optimum performance, the operation of the device must be
performed in accordance with these Instructions for Use. Maintenance should
be performed only by trained personnel authorized by the manufacturer.

1.2 Intended Use

The AII-3000 Series Oxygen Analyzers are intended to measure and display
the concentration of oxygen in compressed breathing air tanks intended for

scuba diving, for personnel safety, area monitoring, O2 deficiency in confined

spaces, checking breathing air tanks and confirming the O2 levels prior to
welding.

1.3 Device Description

The AII-3000 Series Oxygen Analyzers can be positioned on a table top or
pole (tripod wire stand and V-mount dovetail attachments are mounted on the
back of the device) and are readily portable from one location to another.
They provide continuous, fast, reliable and accurate oxygen measurements of
up to respiratory care systems.

The devices utilize an electrochemical galvanic fuel cell type oxygen sensor of

the type that is extensively used to measure oxygen concentrations from 0%

to 100% in gas streams. Oxygen, the fuel for this electrochemical transducer,
diffusing into the sensor through a gas permeable membrane reacts chemical­ly at the sensing electrode to produce an electrical current output proportional
to the oxygen concentration in the gas phase. The sensor has 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 the specified useful life and drops off sharply at the end. The
sensor itself requires no maintenance and is simply replaced at the end of its
useful life like a battery. Inasmuch as the sensor is a transducer in its own

right, its expected life is not affected by whether the analyzer is ON or OFF.

A battery powered state-of-the-art micro-processor converts the sensor’s sig-
nal output representing the partial pressure of oxygen in the gas stream being
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 supplied with every device.

3 Safety Warnings

ALWAYS follow the statements below as they are essential to reduc­ing the risk of use error due to ergonomic features of the device or the
environment in which the device is intended to be used.

 Only trained personnel who have read, understand and agree to follow

the Instructions for Use should operate the device.

 Retain the Instructions for Use for future reference.
 Refer service needs to trained authorized personnel. Failure to do so may

cause the device to fail and void the warranty.

 Inspect the device and accessories before operating and ensure: (a)

there is no evidence of physical damage; (b) the sensor (particularly the
sensing surface) and electrical connections are dry; and, (c) the sensor is
installed and upstream from any humidifying device for accurate calibra­tion and oxygen readings.

 Calibrate: (a) with a known source of air or dry 100% oxygen before

using each day or after 8 hours of continuous use; (b) when the temper-

ature or pressure of the operating environment changes; (c) if the oxy­gen sensor has been disconnected and reconnected; (d) after the battery
or oxygen sensor has been replace.

 Sampling flowing gas: (a) install the optional flow diverter and tee-

adapter in a vertical position as shown in Section 4.3 and (b) assure
there is a tight fit between the flow diverter and tee adapter.

 Sampling static, ambient or controlled atmospheres remove the flow

diverter.

 Clean the device and accessories in accordance with Section 6.1.2.

 Battery replacement Section 6.2: (a) replace the batteries within twenty-

four (24) hours of the battery symbol appearing on LCD display and (b)
calibrate the analyzer after replacing the batteries.

 Oxygen sensor installation or replacement Section 6.3: allow the new

sensor to stabilize for 15-20 minutes in ambient air before attempting to
calibrate.

 Store the device by turning the power OFF and removing the batteries if

the device will not be operated for over thirty (30) days.

 Attempt to repeat the procedure that caused a perceived malfunction

and refer to troubleshooting hints in Section 7 before concluding the

 If the reading is unstable or a malfunction is suspected.
 After the battery symbol appears in the LCD display.
 Near equipment capable of emitting high levels of electromagnetic radia-

tion (EMI) or radio frequency interference (RFI).

 Expose the device; particularly the LCD display or sensor to sources of

extreme heat, cold or excessive sunlight beyond the device’s storage tem-

perature range, refer to Section 8 for extended periods of time.

 In a gas stream with a vacuum greater than 14” water column.
 Immerse the device, oxygen sensor or coiled cable in any liquid.
 Outside of the parameters specified in Section 8 particularly at flow rates

greater than 10 liters per minute - the backpressure generated produces
erroneously high oxygen readings.

 Calibrate: (a) with 20.9% oxygen or room air with the intent of taking

oxygen measurements at oxygen levels above 30% oxygen; (b) in a hu­midified gas stream or atmosphere; (c) without allowing a newly installed
sensor to stabilize for 15-20 minutes in ambient air.

 Attempt to sterilize, autoclave, liquid sterilize, immerse in any liquid or

expose the device or accessories to steam, ethylene oxide or radiation
sterilization.
