Portable Oxygen Monitor Introduction Teledyne Analytical Instruments 9 Introduction Teledyne Analytical Instrument s MX300-I Oxygen Monitor with alarms here after referred to as MX 300-I is a portable instru ment that provides fast and accurate oxygen monitoring and incorporates an audio/visual alarm capability.
Introduction MX300-I Teledyne Analytical Instruments 10 Options for alternate display config uration). An integral battery life indicator is displayed “on demand” with the MX300-I. The instrument is powered by th ree AA alkaline batteries and is designed to operate for 2000 hours in non-alarm state.
Portable Oxygen Monitor Introduction Teledyne Analytical Instruments 11 1.2 Features The MX300-I is a compact, versatile instrument capable of rapidly measuring the oxygen content of an atmosphere or environm ent accurately to ±2% over the ra nge 0-100% oxygen.
Introduction MX300-I Teledyne Analytical Instruments 12 Section 2.1.5. In addition to the above instru ment configuration options, the following optional equipment is ava ilable for your instrum ent: .
Portable Oxygen Monitor Introduction Teledyne Analytical Instruments 13 is illuminated on the LCD and the audible and visual alarms are activated whenever a fault is d etected. 1.5.1 Sensor The MX300-I uses the Teledyne Class R17MED disposable oxygen sensor.
Introduction MX300-I Teledyne Analytical Instruments 14 The oxygen level is calculated a nd then displayed on the liquid crystal display (LCD) on the front panel. In the MX300-I monito r, user-programmed hi gh and low alarm set points are stored in random access me mory (RA M), which resi des within the microprocesso r.
Portable Oxygen Monitor Operation Teledyne Analytical Instruments 15 Operation Note: Upon receipt, INSPECT THE ENTIRE UNIT FOR DAMAGE. Check the unit and a ll included accessories for broken or loose parts. If damaged, DO NOT USE. Notify the shipper, and consult Teledyne Analytic al Instruments.
Operation MX300-I Teledyne Analytical Instruments 16 2.1.1 Sensor Installation or Replacement Note: The R17MED oxygen sensor must be installed before the oxygen analyzer/monitor can be operated 1. Remove the new sensor from its protective bag. Inspect the sensor for damage or electrolyte leakage.
Portable Oxygen Monitor Operation Teledyne Analytical Instruments 17 Figure 2-2: Sensor Cable Connection to Monitor Note: When the MX300-I instrument is used for diffusion sampling (i.e., incubators, tent s, etc.), the plastic flow diverter must be removed from the R17MED sensor.
Operation MX300-I Teledyne Analytical Instruments 18 2.1.2 Mounting The MX300-I can be mounted in several ways depending on the optional equipment ordered at the time of purchase.
Portable Oxygen Monitor Operation Teledyne Analytical Instruments 19 2.1.3 Battery Installation Note: Three “AA” alkaline batteries must be installed in the unit before the monito r will operate.
Operation MX300-I Teledyne Analytical Instruments 20 4. Re-install the battery compar tment door. W hen the unit is first turned on the display will m omentarily display all LCD segments. During this period diagnostic tests are being conducted to insure the circu its are functioning correctly.
Portable Oxygen Monitor Operation Teledyne Analytical Instruments 21 made to the settings. If the batt eries have just been installed the LCD will flash 00.0 4. As with most oxygen analyzer (s) the highest level of accuracy is achieved when cal ibration is conducted using 100% oxygen.
Operation MX300-I Teledyne Analytical Instruments 22 Figure 2-8: Setting the Alarms should never be used where a high degree of accuracy is needed. Note: Never calibrate the unit in humidified gas, as water vapor makes the oxygen concentration appear lower than it really is.
Portable Oxygen Monitor Operation Teledyne Analytical Instruments 23 designed to prevent cr ossing of HI/LO alarm settings. If you attempt to set the LO alarm hi gher than the HI alarm , it will push the HI alarm setting up as you continue to rise the LO alarm set point.
Operation MX300-I Teledyne Analytical Instruments 24 Figure 2-9: 0-1 VDC or RS 232 Digital Output Port If your instrument is set fo r analog (0-1 VDC) output, you can reconfigure it to use the digital output by changing a jumper on the internal PC board.
Portable Oxygen Monitor Operation Teledyne Analytical Instruments 25 2.2 Use 2.2.1 Procedure Note: Prior to use, always test the batteries and alarms (if applicable).
Operation MX300-I Teledyne Analytical Instruments 26 R17MED sensor so that it does not in terfere with the rapid exchange of gases to and from the sensing surface of the sensor. CAUTION: FAILURE TO REMOVE THE DIVERTER IN T HESE APPLICATION AREAS WILL RESU LT IN A MARKED LOWERING OF THE RESPONSE TIME OF THE SENSOR.
Portable Oxygen Monitor Operation Teledyne Analytical Instruments 27 2.3.2 T emperature The R17MED oxygen sensor adjusts for ambient temperature changes in the range of 0–40°C (32–106° F).
Operation MX300-I Teledyne Analytical Instruments 28 2.3.4 Discrepancy in Readings The MX300-I instrument should be used to measure the oxygen concentration exiting another oxygen mixing device or life support system (i.e., a blender, incubato r or anesthes ia machine).

Operation MX300-I Teledyne Analytical Instruments 30 After exposure to nitrous oxide mixt ures, the sensor should be left in 100% oxygen overnight (e.g., left in a breathing circu it that has been flushed with pure oxygen). If this is not practical, when using the Tee, remove the plastic flow diverter and l eave the sensor in room air.
Portable Oxygen Monitor Operation Teledyne Analytical Instruments 31 • Test batteries regularly and re place when battery indicator shows low battery (no bars remaining) • Make sure keys are locked by using the LOCK/UNLOCK key feature. • Keep the unit, sensor and connections dry, or on the dry side of the breathing circuit.
Operation MX300-I Teledyne Analytical Instruments 32 • Use cleaning agents or liquids in the cable receptacles o r around the battery compartment. • Place the unit itself in a water vapo r-saturated environment. • Expose the LCD to excessive sunlight.
