DocumentDocumentO2 Portable Quick Start Guide 2. O2 Compensation chart The O2 compensation chart should be used to check that the O2 Portable is reading correctly in hot and humid conditions, as the higher the temperature and humidity the less atmospheric oxygen there is. An air calibration should be performed prior to checking any samples and the O2 Portable should be adjusted as per the below chart. 4. Operation DII flow adaptor 1] The Analox O2 Portable comes complete with the unique DII adaptor which allows to you to directly apply the Analyzer to the outlet on your nitrox tank. 2] Connect the DII adaptor to the Analyzer by pushing the adaptor over the sensor turret. The o-ring on the sensor should ensure a comfortable fit. 3] Hold the DII adaptor firmly against the cylinder outlet facing you. Very slowly open the pillar valve until gas can just be heard hissing through the flow adaptor. WARNING: OPEN THE CYLINDER VALVE SLOWLY AS HIGH PRESSURE CAN RESULT IN DAMAGE TO THE SENSOR. www.analoxgroup.com/products/o2-portable Scan the QR code to visit the Analox O2 Portable web page Document ref: MO2-870-01 1. Introduction The O2 Portable Oxygen Analyzer is designed to measure oxygen levels in the range 0.1 100% O2. The Analyzer should be used for cylinder oxygen level verification or for monitoring a gas mixing panel but should not be used for both. If the Analyzer is used for measuring the oxygen level in the output from a mixing panel, another O2 Portable should be used for cylinder verification purposes. The O2 Portable has a large digital display and operates from an internal temperature compensated 3-year life (Expected) electrochemical oxygen sensor. Power is provided by a 9V, 4000-hour life battery giving up to 3 year operation before replacement is necessary. The O2 Portable is a water-resistant drop resistant totally self-contained unit designed specifically for all the diving industry Sport (NITROX), Commercial and Military where hostile environmental conditions are the norm not the exception. Your O2 Portable is supplied ready to use. On receipt of the unit, please check for damage. If there is any damage, contact your supplier. WARNING: IT IS IMPORTANT THAT THESE INSTRUCTIONS ARE READ BEFORE USE. 4] Close the pillar valve after fifteen seconds when a stable reading is observed on the O2 Portable. 5] If in doubt repeat the procedure taking care to ensure a very low gas flow. 6] Note that after a few seconds of the gas flow being stopped the reading will begin to change towards the level in the surrounding air of 20.9% O2 you should therefore take the reading while flow is ON. WARNING: DO NOT PRESSURISE THE SENSOR, THIS WILL RESULT IN INACCURATE READINGS. 3. Air calibration Air calibration is essential before every use and is performed as follows: 1] Ensure that any flow adaptors are removed and the reading on the display has stabilised. 2] Expose the Analyzer to clean air for two minutes and adjust the calibration knob until the display reads the correct value using the humidity chart above. If this is not possible refer to section 5 Troubleshooting and section 6 Maintenance. 3] It is possible that at very high altitude normal calibration is not achievable. In this event you must ascertain the actual pressure in BAR and multiply the atmospheric oxygen percent (20.9%) by this pressure and set the reading during calibration to the calculated level (this is the surface equivalent oxygen percentage). When you measure the level of oxygen in the sample you must divide the reading by the same atmospheric pressure value to obtain the true percentage of Oxygen in your sample. For Example: At an atmospheric pressure of 0.8 BAR the surface equivalent oxygen percentage is 20.9% x 0.8 = 16.7%O2 Surface Equivalent. If the reading you then obtain from your sample is 32.0% you must divide this by 0.8 to obtain the true Oxygen percentage, 32.0/0.8 = 40.0%O2 True Percentage. 5] The Analyzer is now ready for oxygen measurement. WARNING: THE ANALYZER IS SENSITIVE TO OXYGEN PARTIAL PRESSURE. CALIBRATION MUST ALWAYS BE CARRIED OUT AT THE SAME ATMOSPHERIC PRESSURE AS OXYGEN MEASUREMENT. 5. Troubleshooting Symptom Reason Solution Battery symbol Low battery Change battery No display Zero reading Switched off Bad connection Dead battery Sensor disconnected Sensor expired Switch on Check display connection Check battery connection Check connection Change sensor Reading erratic Reading does not change when calibration knob is turned Display segments missing Will not calibrate Reading drifts Pressure on sensor Radio transmission Sensor old or faulty Condensation on sensor Check flow Move unit away Change sensor Dry sensor face Faulty connections Sensor failure Check connections, Change sensor Display faulty Sensor faulty Sensor not in air High altitude Rapid temperature change Return to dealer Change sensor Check flow adapter Calculate percent equivalent =20.9%xbar Do not move Analyzer from one temperature to another immediately before use 6. Maintenance Battery replacement 1] Remove the 4 screws located at each corner of the unit and carefully lift the lid. 2] Slide the battery out of its spring bracket and disconnect the lead. 3] Connect the lead to the new battery and slide the battery behind the spring bracket. 4] Replace the lid carefully and screw down taking care that the sensor locates properly. Ensure that you do not trap any wires. Sensor replacement 1] Remove the 4 screws located at each corner of the unit and carefully lift the lid. 2] Remove the flow adapter if fitted and slide the sensor out of the lid. 3] Disconnect the in line sensor connector. 4] Dispose of the old sensor according to local regulations for Lead and Potassium Hydroxide solution. 5] Remove the new sensor from its bag and check it for leaks, connect to the inline connector and slide through the lid. 6] Replace the lid carefully and screw down taking care that the sensor locates properly. Ensure that you do not trap any wires. 7.

Safety information Battery 1] When the life of the battery has expired it should be disposed of safely in accordance with local regulations. Sensor 1] When the life of the sensor has expired or it is leaking or otherwise damaged it must be disposed of safely in accordance with local regulations. 2] The sensor contains KOH Potassium Hydroxide solution which is hazardous and can have the following effects: · Skin Potassium Hydroxide is corrosive skin contact could result in a chemical burn. · Ingestion Can be harmful or FATAL if swallowed. · Eye Contact can result in the permanent loss of sight. First aid procedures · Skin · Ingestion · Eye Wash the affected part with a lot of water and remove contaminated clothing. If stinging persists get medical attention. Drink a lot of fresh water. Do not induce vomiting. Get medical attention. Wash with a lot of water for at least 15 minutes and get medical help immediately. 9. Care of the O2 Portable 1] Although designed to be water resistant the O2 Portable should not be intentionally immersed in liquid or left outside unprotected. 2] The O2 Portable is built to resist the effects of day to day shocks and drops but remember it is a precision oxygen analyzer and should be looked after carefully to give long trouble free service. 3] To clean the O2 Portable use a damp soft cloth. 4] Protect the O2 Portable from long periods of direct sunlight and do not subject it to high or low temperature extremes.
