2.0 OPERATING INSTRUCTIONS
2.1 Oxygen, Flow and Pressure Measurement
To check oxygen concentration, flow and pressure of a gas sample from a concentrator:
1. Connect the gas sample tubing to the gas sample inlet of the UltraMaxO2.
2. Attach the other end of the gas sample tubing to the oxygen concentrator.
3. Initiate the flow of gas to the UltraMaxO2at 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.
4. Turn on the UltraMaxO2.
5. Allow the oxygen reading to stabilize for approximately 10 seconds before reading
the oxygen concentration and flow.
6. To check pressure, cover the gas sample outlet with thumb or finger while gas is
flowing.
7. Wait 5 seconds for the display to read pressure.
2.2 Switching Pressure Units of Measure
The UltraMaxO2can measure pressure in PSI or kPa. The UltraMaxO2is factory set to
measure in PSI. To switch to kPa:
1. Using a #1 Phillips screwdriver loosen the battery door screw and remove the
battery door.
2. Toggle the switch inside the battery compartment.
3. Replace the battery door and tighten the battery door screw.
2.3 Calibration Verification Procedure
A calibration verification mode is provided to verify that the UltraMaxO2is functioning
properly. To perform the calibration verification:
1. Turn on the UltraMaxO2.
2. Connect a source of pure oxygen (≥99.95%) to the gas sample inlet.
3. Flow 2-5 LPM of gas into the UltraMaxO2. Ensure that the gas flowing to the
UltraMaxO2is at a stable temperature.
4. 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 Customer Service. Calibration
verification mode is indicated by “CAL” and “VER” flashing on screen beneath the
gas measurement .

866.4.Maxtec www.maxtecinc.com4
3.0 FACTORS INFLUENCING ACCURATE READINGS
3.1 Effects of Temperature
The UltraMaxO2compensates for temperature and will perform within specifications
throughout the operating temperature range. However, taking measurements during
rapid changes in gas temperature should be avoided.
3.2 Effects of Humidity
The UltraMaxO2has 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 UltraMaxO2. 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 UltraMaxO2.
3.3 Effects of Other Gases
The UltraMaxO2is 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 UltraMaxO2to
measure oxygen concentration incorrectly.
3.4 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 UltraMaxO2 requires that the ratio of oxygen to argon remain constant in
order to guarantee an accuracy of +/-1.5% oxygen.
• DO NOT use the UltraMaxO2 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.
4.0 ERROR CODES
The UltraMaxO2 has self diagnostic features built into the software to detect
faulty readings outside of normal operating ranges. The codes, descriptions and
recommended actions are:
• E01: Oxygen measurement out of range Hi (≥102.0% calculated by algorithm).
Recommended Action: Verify that the UltraMaxO2is being used in the correct
mode (Concentrator or Calibration Verification mode). If error code repeats;
perform a calibration verification per section 2.3 of this manual. If error code
repeats again; contact Customer Service.

866.4.Maxtec www.maxtecinc.com 5
• E02: Oxygen measurement out of range Low (≤-2.0% calculated by algorithm).
Recommended Action: Verify that the UltraMaxO2is being used in the correct
mode (Concentrator or Calibration Verification mode). If error code repeats;
perform a calibration verification per section 2.3 of this manual. If error code
repeats again; contact Customer Service.
• E03: Device memory corrupt or missing.
Recommended Action: Return the UltraMaxO2to the manufacturer for factory
repair.
• E04: Signal reading not stable.
Recommended Action: Return the UltraMaxO2to the manufacturer for factory
repair.
• E05: Pressure measurement out of Range Hi (≥50 PSI).
Recommended Action: Check the pressure on a known gas source pressure. If
error code repeats; contact Customer Service.
• E06: Outside of operating temperature Hi (≥40° C).
Recommended action: The UltraMaxO2is too hot, cool the device closer to room
temperature before use.
• E07: Outside of operating temperature Low (≤15° C).
Recommended action: The UltraMaxO2is too cold, warm the device closer to room
temperature before use.
• E08: Device self check found error.
Recommended Action: Remove and replace the batteries. If error code repeats;
return the UltraMaxO2to the manufacturer for factory repair.
5.0 CHANGING THE BATTERIES
Batteries should be changed when the battery icon illuminates. The battery icon will
remain lit until the batteries are changed. If the battery power level is too low the
UltraMaxO2will not power on until the batteries are changed.
5.1 Battery Replacement Procedure
1. Using a #1 Phillips screwdriver loosen the battery door screw and remove the
battery door.
2. Remove the batteries.
3. Insert new batteries ensuring correct placement. DO NOT use rechargeable
batteries.
4. Replace the battery door and tighten the battery door screw.
5. If the UltraMaxO2does not power on when done verify the batteries are installed
correctly and that the batteries are fresh.
6.0 CLEANING AND MAINTENANCE
• Use caution to prevent any fluid from entering the UltraMaxO2.
• DO NOT soak or immerse the UltraMaxO2 in fluid.
• DO NOT autoclave or expose the UltraMaxO2to ethylene oxide sterilization.
6.1 Cleaning
• Wipe down the exterior surfaces of the UltraMaxO2with a moist cloth and mild
hand or dish soap (pH 6-8).

866.4.Maxtec www.maxtecinc.com6
6.2 Maintenance
