Calibration Procedure (required for annual calibration)
Equipment 5% CO
2
calibration gas cylinder with CO
2
sample line (kit available from Scott Medical
Products, PN 4653ORF-BD)
Procedure
1. On the Propaq M, do the following to enter the CO
2
Calibration control panel:
• Press the CO
2
quick access key ( ).
• Use the navigation keys to select Supervisor>Service>Diagnostic>CO
2
>Calibration.
2. Connect the Propaq M to the 5% CO
2
calibration gas cylinder using the sample line included
with the calibration kit.
3. From the CO
2
Calibration Menu, select Calibration.
4. Activate the calibration gas flow by pressing the top valve on the calibration gas canister.
5. Continue to apply the calibration gas until the status in the CO
2
Calibration control panel
displays: CALIBRATION GAS CAN BE REMOVED.
• When the calibration is complete, the status in the CO
2
Calibration control panel
displays: CALIBRATION DONE - OK OR CALIBRATION DONE - ERROR.
6. To verify calibration, perform the CO
2
Calibration Check Procedure on page 10.
Acceptable Results
The status in the CO
2
Calibration control panel displays: CALIBRATION DONE - OK.
Perform the above calibration check procedure to verify CO
2
accuracy.
The calibration date will be updated upon exiting the CO
2
Test control panel.
Corrective Action
If an error is reported, refer to the table below for possible causes.
If readings fail to meet the required accuracy, the CO
2
module requires replacement or factory
analysis and realignment.
The following table describes possible calibration errors and likely causes.
Table 1-1. Calibration Errors
Error Message Cause
No gas or wrong gas
concentration The concentration of supplied gas is not close to the expected
value.
No stable gas flow and
Calibration failure The gas sample is not stable, i.e. due to leak or noise.
Measurement error Occlusion detection during known gas sampling.
Measurement error Sample line disconnection during gas sampling.
AZ fail The Auto Zero that is part of the calibration process failed.
Calibration aborted by
user Calibration mode canceled during gas sampling.
