Calibration Calibration Procedures
NOTE: If the system is going to be used during the calibration,
insert the O 2 cell plug into the port from which the oxygen
sensor was removed using a push and turn motion.
a. Select 21% to enter the 21% oxygen concentration calibration screen.
b. Remove the oxygen sensor from the Breathing System and expose it to room air for
at least 3 minutes.
c. Flush the O 2 sensor with air from the auxiliary output for 5-10 seconds to ensure that
no O 2 bubbles are trapped in the sensor.
d. Select Next to start 21% oxygen concentration calibration.
NOTE: The O 2 sensor voltage is displayed during the calibration.
This is the amplified O 2 cell voltage at the A/D converter for
the oxygen sensor. The O 2 sensor voltage is not displayed
for UI versions 2.24 and lower.
e. When calibration is successfully completed, install the oxygen sensor into the
Breathing System.
NOTE: The oxygen sensor must be installed in the Breathing
System for 10 minutes prior to 100% oxygen concentration
calibration to adjust to the temperature of the system.
f. Press the O 2 Flush button for 5-10 seconds to clear out any non-O 2 gases from the
system.
g. Expose the oxygen sensor to 100% pure oxygen (5 L/min) for at least 3 minutes.
h. Select 100% to enter the 100% oxygen concentration calibration screen.
i. Select Next to start 100% oxygen concentration calibration.
