    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.

    The bar graph indicator is continuously on when the analyzer is powered on. 2.1.4 Calibration The AX300 should be calibrated before each use and every 8 hours to main- tain 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.

    1-2 liters per minute. Note: An accessory calibration assembly (P/N C53790) is available from Teledyne for use with the R17MED sensor 5. Wait about 20 seconds to ensure that the sample line is completely purged with the calibration gas.

    Once the analyzer reaches the locked mode, press the LOCK/UNLOCK key and press the CAL key to repeat calibration. Note: The AX300 can only be calibrated using certified medical grade 100% oxygen or ambient level air (20.9% Oxygen). Improper calibration or use of other gas con- ...

    Note: Prior to every use, always test the batteries, check the sensor for any leaks or damage, and check the analyzer calibration. The AX300 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 24: Factors Affecting Sampling Accuracy

    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 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.
  • Page 25: Discrepancy In Readings

    2.3.4 Discrepancy in Readings When a discrepancy in oxygen readings is detected, the oxygen analyzer’s readings should be verified by checking the AX300 battery condition and cali- bration using 100% oxygen. If the analyzer can be calibrated, the unit can be as- sumed to be in good working order.

    * Errors are approximate and may vary based on exposure times and concentra- tions. These performances meet or exceed the requirements of ISO 7767: 1997 (E). CAUTION: THE AX300 SHOULD NOT BE USED IN THE PRESENCE OF FLAM- MABLE ANESTHETICS SUCH AS DIETHYL ETHER OR CYCLOPRO- PANE. CAUTION: THE ANALYZER, THE OXYGEN SENSOR AND ASSOCIATED HARDWARE ARE NON-STERILE DEVICES.
