Calibration takes approximately 1 minute and 50 seconds. During the calibration
process, gas flow is temporarily shut off. Following the gas flow shut off:
• If the O2 blending gas is air, the FiO
2
knob automatically adjusts to 21% and
then to 100%.
• If the O2 blending gas is 95% oxygen / 5% carbon dioxide, the FiO
2
knob
automatically adjusts to 95% and then to 100%.
Then the flow rate is set to 5 L/min and then 2 L/min. The Gas subtab screen will
change as indicated in the following picture. The Gas icon on the screen will display
CAL, and control of the gas system will be disabled from the CCM for the duration of
the calibration. After calibration, the gas flow and FiO
2
setpoints are returned to the
values set prior to calibration.
Note:
Do not obstruct the gas flow outlet during calibration as this may affect the
accuracy of the calibration.
Note:
Do not attempt to change the gas flow rate or the FiO
2
via the local control
knobs during calibration as this will cause the calibration to fail.
After a Successful Calibration:
A successful calibration is indicated by the following items:
• The label for
Calibration Status
in the Gas subtab within the Setup tab is “PASS”.
• CAL
is removed from the %O2 icon.
• “O2 Analyzer Calibration is Complete” is displayed in the message area at
the top of the CCM window. Note that this message may not be displayed in
the message area if a higher priority message is present.
Check the Messages subtab within the
Aux
tab to verify that a successful calibration
has been performed. The “O2 Analyzer Calibration Complete” message will be
present.
