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.
