Portable Oxygen Analyzer Introduction

Teledyne Analytical Instruments 1

Introduction

The Teledyne Analytical Instruments AX300 Oxygen Analyzer, he-

reinafter referred to as AX300 or analyzer, is a portable analyzer de-

signed to analyze oxygen concentration in medical gas mixtures. Oxy-

gen analysis is linear across the single range of 0-100% using Tele-

dyne’s class R17MED oxygen sensor.

Figure 1-1: AX300 Front View

The AX300’s liquid crystal display (LCD) consists of up to 3.5

characters plus a decimal point indicator capable of displaying up to

105%. An integral battery life indicator is displayed continuously on the

AX300.

The analyzer is powered by three AA alkaline batteries and is de-

signed to operate for 2000 hours on a single set of batteries in a Non-

alarm State.

A sensor failure alarm is incorporated which warns the user if the

sensor signal is lost or low. When this occurs, the √SENSOR display

and a visual green light will flash, and the alarm buzzer will activate.

This alarm condition is also triggered when the oxygen concentration at

the point of analysis falls below 18% (Reference: ISO 7767 standard).

For safety reasons, the audible alarm cannot be silenced until the alarm

condition is resolved.

CAUTION: DURING NORMAL USE, ALARM CONDITIONS SHOULD

NOT BE OVERRIDDEN BY ACTIONS SUCH AS HOLDING

THE ALARM SILENCE KEY DEPRESSED OR REMOVING

THE BATTERIES. THE CAUSE FOR THE ALARM CONDI-

TION SHOULD FIRST BE RESOLVED.

CAUTION: WHILE HOLDING DOWN THE ALARM SILENCE KEY MAY

MOMENTARILY SILENCE THE ALARM BUZZER, AUDIBLE

ALARM WILL RETURN UPON DISENGAGING THE ALARM

SILENCE KEY. HOLDING THE KEY FOR LONGER DURA-

TIONS WILL INITIATE THE “STUCK KEY” ALARM, WHICH

CAN BE DEACTIVATED ONLY VIA REMOVING THE BAT-

TERIES FROM THE ANALYZER. ANALYZER SHOULD BE

RECALIBRATED UP ON REPOWERING THE ANALYZER.

NOTE: THE ALARM SILENCE KEY DOES NOT PLAY ANY ROLE IN

THIS VERSION OF THE ANALYZER. IT IS DESIGNED IN

FOR ANY POSSIBLE FUTURE PRODUCT MODIFICATION.
