5.2 Pressure Monitor Functional Test
A Pressure Monitor Functional Test may be performed anytime to quickly verify the function of
the pressure monitor and alarms.
1. Turn the device on and zero the pressure reading. (See section 2.3.5)
2. Connect the pressure monitoring line to the pressure monitoring port on the device.
3. Adjust the low pressure alarm to 3 cmH2O and the high pressure alarm to 7 cmH2O.
4. Fill a graduated container with water to the 0 cm line as shown. Markings on the
container should be in centimeters (cm). Refer to diagram below.
5. Submerse the end of the pressure monitoring line into the cylinder to the 5 cm
marking. Verify the pressure reading is 5 cmH2O ±1 cmH2O.
6. Lower the tubing below the 7 cm line. Verify the high pressure alarm and LED turn on.
7. Raise the tubing above the 3 cm line. Verify the low pressure alarm and LED turn on.
8. Remove the tubing from the water and verify the pressure reading returns to 0.0
cmH2O. Contact Maxtec technical service if the device fails to function as expected.
6.0 TROUBLESHOOTING
The MaxO ME+p monitors have a self test feature built into the software to detect faulty
2
calibrations, oxygen sensor failures, and low operating voltage. These are listed below, and
include possible actions to take, if an error code occurs.
NOTE: The operator must be facing the device and positioned within 4 meters to distinguish
the visual alarm indicators. Audible alarms can be distinguished as long as the operator is in
the same room and the ambient noise level is typical for a clinical setting.
E01: Calibration error, sensor output lower than expected. See applicable note at end of
Trouble shooting section.
E02: No sensor attached. Reconnect sensor, see applicable note at end of Trouble shooting
section.
E03: No Valid Calibration Data Available, make sure unit has reached thermal equilibrium and
perform a calibration routine.
E04: Battery Below Minimum Operating Voltage, replace batteries. A medium priority alarm will
sound every 25 seconds until the batteries are replaced or become too dead to sound the alarm.
E05: Calibration error, sensor output higher than expected. See applicable note at end of
Trouble shooting section.
E06: Non-compatible oxygen sensor. Reconnect sensor, see applicable note at end of Trouble
shooting section.
E07: Calibration error, sensor output is not stable. See applicable note at end of Trouble shoot-
ing section.
E08: Calibration error, battery too low to preform calibration. Replace batteries and re-calibrate.
E09: Pressure out of range, too high. The pressure applied to the monitor port has exceeded
the device maximum pressure. Remove the pressure or adjust within the allowable range.
E10: Pressure out of range, too low. The pressure applied to the monitor port has exceeded the
device minimum pressure. Remove the pressure or adjust within the allowable range.
E11: Pressure zero calibration unstable. Ensure pressure is stable and attempt a new zero cali-
bration. If error persists, contact Maxtec technical service.
E12: Pressure CAL/0 out of range.
ENGLISH
E13: Pressure sensor error. No valid pressure sensor data. Remove batteries from device to
reset and perform a new CAL/0. If error persists, contact Maxtec technical service.
NOTE: If you receive a E01, E05, or an E07 error code, correct by ensuring the calibration gas is
either room air or 100% oxygen. Also ensure the calibration gas flow, pressure and concentra-
tion is constant. Allow sufficient time for the sensor to stabilize in the calibration gas and with
room temperature, then attempt to calibrate again.
If these steps do not correct the error, contact Maxtec for technical support.
NOTE: Use only a Maxtec approved Max-550E sensor called out in Section 10.0 Spare Parts and
Accessories. The Max550E sensor is equipped with an authentication chip to ensure the moni-
tor is used with an approved sensor.
NOTE: Correcting E02 or E06 errors:
1. Disconnect the sensor and reconnect, making sure the male plug is fully inserted into
the receptacle before tightening the threaded locking shroud. The analyzer should now
perform a new calibration with the error cleared.
2. If the error still persists, remove the batteries and external power, wait 30 seconds,
then reinstall to perform a factory reset and diagnostic on the analyzer. The analyzer
should again perform a new calibration with the error cleared.
3. Contact Maxtec Customer Service Department if the error code cannot be cleared.

/ flow diverter that come in contact with gas delivered to the patient should not become
contaminated. If you suspect that the sensing face of the sensor or internal surfaces of the
T-adapter / flow diverter have become contaminated, these items should be discarded and
replaced. Store the MaxO
1. Using Super Sani-Cloth germicidal disposable wipes (medical grade 2-in-1 cleaning /
disinfecting wipes) remove all visible contamination from the external surfaces of the
device and its accessories. Be sure to closely inspect and remove contamination from
seams and recesses on the device that may trap contaminants.
2. After all visible contamination is removed, use a second germicidal wipe to thoroughly
wet the surfaces of the device and accessories. Allow to remain wet for 4 minutes. Use
additional wipes if needed to assure surfaces are wetted continuously for 4 minutes.
3. Allow device to air dry.
4. Visually inspect each component for visible contamination.
CAUTION: Excessive rubbing of labels may cause them to become illegible.
NOTE: Be sure to thoroughly clean and disinfect the areas depicted. These regions are con-
tacted during normal use and may contribute to cross contamination if not disinfected prop-
erly. To prevent overcleaning, if sanitation is required, sanitization should be limited to once
between each patient use. Other necessary cleanings should be done with a germicidal wipe
or mild detergent and water.
NOTE: the device should be discontinued from service if material degradation or cracking are
observed.
DO NOT spray cleaning solutions directly onto the monitor, sensor or buzzer opening.
DO NOT immerse the MaxO
DO NOT use strong solvent cleaners.
DO NOT allow cleaning liquids to contact the face of the sensor as this may impair the
readings of the sensor.
DO NOT attempt to sterilize the MaxO
DO NOT allow liquids to enter the pressure monitor port.
