26.6 Calibrating CO2
For sidestream and microstream CO2 modules, a calibration is needed every year or when the
measured values have a great deviation. For maintream CO2 module, no calibration is
needed.
Tools required:
„ Gas bottle, with 4%, 5% or 6% of CO2.
„ T-shape connector
„ Tubing
Follow this procedure to perform a calibration:
1. Make sure that the CO2 module has been warmed up or started up.
2. In the main menu, select [
Maintenance >>
] → [
User Maintenance >>
] → enter the
required password and then select [
Maintain CO2 >>
] from the popup menu.
3. In the [
Maintain CO2
] menu, select [
Zero
].
4. Connect the gas bottle with the tubing using a T-shape connector as shown below.
Check the airway and make sure there are no leaks.
5. Open the gas valve and vent CO2 into the tubing.
6. In the [
Calibrate CO2
] menu, enter the vented CO2 concentration in the [
CO2
] field.
7. In the [
Maintain CO2
] menu, the measured CO2 concentration, barometric pressure,
sensor temperature and current flowrate are displayed. After the measured CO2
concentration becomes stable, select [
Calibrate CO2
] to calibrate the CO2 module.
8. If the calibration is finished successfully, the message [
Calibration Completed!
] is
displayed. If the calibration failed, the message [
Calibration Failed!
] is displayed.
Perform another calibration.
