OPERATING INSTRUCTIONS
Oxygen, Flow and Pressure Measurement
To check oxygen concentration, flow and pressure of a gas sample from a concentrator:
Connect the gas sample tubing to the gas sample inlet of the UltraMax O2.
- Attach the other end of the gas sample tubing to the oxygen concentrator.
- Initiate the flow of gas to the UltraMax O2 at a rate of 1-10 liters per minute (2 liters per minute is recommended). Ensure the concentrator’s output is stable per the concentrator manufacturer’s recommendations.
- Turn on the UltraMax O2.
- Allow the oxygen reading to stabilize for approximately 10 seconds before reading the oxygen concentration and flow.
- To check pressure, cover the gas sample outlet with thumb or finger while gas is flowing.
- Wait 5 seconds for the display to read pressure.
DO NOT hold the mode button while checking a concentrator or the reading will be inaccurate.
Switching Pressure Units of Measure
The UltraMax O2 can measure pressure in PSI or kPa. The UltraMax O2 is factory set to measure in PSI. To switch to kPa:
- Using a #1 Phillips screwdriver loosen the battery door screw and remove the battery door.
- Toggle the switch inside the battery compartment.
- Replace the battery door and tighten the battery door screw.
Calibration Verification Procedure
A calibration verification mode is provided to verify that the UltraMax O2 is functioning properly. To perform the calibration verification:
- Turn on the UltraMax O2.
- Connect a source of pure oxygen (≥99.95%) to the gas sample inlet.
- Flow 2-5 LPM of gas into the UltraMax O2. Ensure that the gas flowing to the UltraMax O2 is at a stable temperature.
- Press and hold the mode button. While holding the mode button, the gas measurement should read between 98.5 and 101.5% oxygen. If the gas measurement is not within this range, call Maxtec Customer Service. Calibration verification mode is indicated by “CAL” and “VER” flashing on screen beneath the gas measurement.
FACTORS INFLUENCING ACCURATE READINGS
Effects of Temperature
The UltraMax O2 compensates for temperature and will perform within specifications throughout the operating temperature range. However, taking measurements during rapid changes in gas temperature should be avoided.
Effects of Humidity
The UltraMax O2 has a humidity sensor to detect and compensate for the humidity of gas entering the device. However, high levels (condensing) of humidity can affect the accuracy and reliability of the UltraMax O2. To prevent possible damage:
Avoid usage in environments of greater than 95% relative humidity.
DO NOT use this device in a breathing circuit.
DO NOT breathe or blow into the UltraMax O2.
Effects of Other Gases
The UltraMax O2 is designed to measure two different types of gas mixtures:
- Oxygen, nitrogen and argon from oxygen concentrators.
- Pure oxygen during calibration verification mode.
Any other concentrations or combinations of gases will cause the UltraMax O2 to measure oxygen concentration incorrectly.
Effects of Low Flow
Oxygen concentrators function on the principle of removing nitrogen gas from air, leaving concentrated oxygen and argon at a specific oxygen to argon ratio. This operating principle may be altered when concentrators are set to flow at the low end of their operational range. At low flows they may output a low oxygen concentration, e.g. 85% to 91%, for reasons other than high nitrogen, possibly due to an increase in argon content. The UltraMax O2 requires that the ratio of oxygen to argon remain constant in order to guarantee an accuracy of +/-1.5% oxygen.
DO NOT use the UltraMax O2 to measure the oxygen concentration of a concentrator when flowing at rates lower than its optimal performance as specified by the concentrator manufacturer; generally 4 LPM or less on concentrators that have a maximum flow of 10 LPM, and 1 LPM or less on concentrators that have a maximum flow of 5 LPM.
ERROR CODES
The UltraMax O2 has self diagnostic features built into the software to detect faulty readings outside of normal operating ranges. The codes, descriptions and recommended actions are:
