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:
Connect the gas sample tubing to the gas sample inlet of the UltraMaxO2.
1. Attach the other end of the gas sample tubing to the oxygen concentrator.
2. 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.
3. Turn on the UltraMaxO2.
4. Allow the oxygen reading to stabilize for approximately 10 seconds before reading the
oxygen concentration and flow.
5. To check pressure, cover the gas sample outlet with thumb or finger while gas is
flowing.
6. 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.
2.2 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:
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 UltraMaxO2 is functioning prop-
erly. To perform the calibration verification:
1. Turn on the UltraMaxO2.
2. Connect a source of pure oxygen (≥99.95%) to the gas sample inlet.
3. Flow 2-5 LPM of gas into the UltraMaxO2. Ensure that the gas flowing to the
UltraMaxO2 is 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 Maxtec Customer Service. Calibration verification mode is
indicated by “CAL” and “VER” flashing on screen beneath the gas measurement.
3.0 FACTORS INFLUENCING
ACCURATE READINGS
3.1 Effects of Temperature
The UltraMaxO2 compensates for temperature and will perform within specifications through-
out the operating temperature range. However, taking measurements during rapid changes in
gas temperature should be avoided.
3.2 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.
3.3 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.
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 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.
4.0 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:
E01: Oxygen measurement out of range Hi (≥102.0% calculated by algorithm). Recommended
Action: Verify that the UltraMax O2 is being used in the correct mode (Concentrator or
Calibration Verification mode). If error code repeats; perform a calibration verification per sec-
tion 2.3 of this manual. If error code repeats again; contact Maxtec Customer Service.
E02: Oxygen measurement out of range Low (≤-2.0% calculated by algorithm). Recommended
