Calibrating the airway module
WARNING
6-8
Calibrate airway modules once every six months or whenever there
are indications of errors in the gas readings. Use a manufacturer
approved calibration gas and regulator to calibrate the modules. See
the "Parts" section for the stock numbers of the calibration gas and
regulator.
Only use manufacturer approved calibration gas. Do not
use any other calibration gases or the calibration will not
succeed. Dispose of calibration gas containers in
accordance with local environmental procedures.
Note
The Calibration menu is not available during Checkout or during a
case.
During gas calibration, % units are used for CO2 regardless of
selected measuring units.
1.
Turn on the power. Let the module warm up for 30 minutes
before starting calibration.
2.
Attach the regulator to the calibration gas cylinder.
3.
Attach a new sampling line to the water trap. Connect the loose
end of the sampling line to the regulator on the calibration gas
cylinder.
4.
Select the System Setup button.
5.
Select Calibration.
6.
Select Airway Gas.
7.
Wait until 'Feed Gas' appears.
8.
For regulators with a numbered gauge, open the regulator until
the gauge reads between 5 to 7 psi (34 to 48 kPa). For
regulators with a non-numbered gauge, open the valve.
9.
Feed the calibration gas until 'Adjust' appears.
•
If an error occurs during calibration or if no gas is fed,
'Calibration error' appears. Push the ComWheel to perform
a new calibration.
•
Do not close the regulator until all the adjustments have
been made.
10. If a gas needs adjustment, select the gas to be adjusted. Use
the ComWheel to change the value until it matches the
calibration gas cylinder value. Push the ComWheel to confirm
the change.
If a gas does not need adjustment, select the gas. Push the
ComWheel to confirm the value.
11. Close the regulator.
