Page 9: Introduction
Introduction The Teledyne Analytical Instruments AX300-I Oxygen Analyzer, hereinafter referred to as AX300-I 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. -

Page 17: Calibration
The bar graph indicator is continuously on when the analyzer is powered on. 2.1.4 Calibration The AX300-I should be calibrated before each use and every 8 hours to maintain accuracy. When batteries are removed for any reason or when new batteries are in- stalled, the oxygen analyzer defaults to the calibration mode with the LCD dis- play flashing 00.0. -

Page 21: Operating Instructions
Note: Prior to every use, always test the batteries, check the sensor for any leaks or damage, and check the analyzer calibration. The AX300-I analyzer can be used to measure a gas mixture for oxygen in two basic modes: In the inhalation side of breathing system upstream of any antibac- ... -
Page 22: Factors Affecting Sampling Accuracy
As with all diffusion based oxygen sensors, excessive condensation on the sensing surface of the R17MED will block the diffusion of oxygen to the sensor, rendering it inoperative. We recommend installing the sensor on the dry side of the breathing system at all times. Teledyne Analytical Instruments... -
Page 23: Temperature
The only time that these analyzers can accurately read per- centages is when the total pressure does not vary over time between calibrations and use. For this reason it is important to calibrate the AX300-I oxygen analyzer (with R17MED oxygen sensor) at regular intervals. It is recommended that the unit be calibrated prior to each use or every 8 hours. -
