This indicates that the module does not leak. If the alarm message disappears, or the flow rate is equal to
10ml/min or greater, it indicates that the module leaks. Perform the leakage test again. If the problem
remains, contact your service personnel for help.
17.11 Calibrating the AG Module
Calibrate the AG module every year or when the measured value is outside the specification. To calibrate the AG
module, contact the service personnel.
CAUTION
Connect the gas outlet to the scavenging system when calibrating the AG module.
17.12 AG Troubleshooting
If the AG airway is occluded, the message AG Airway Occluded appears. In this case, check for the follows until
the message disappears:
1. Check the airway adapter for occlusion and replace if necessary.
2. Check the sample line for occlusion or kinking and replace if necessary.
3. Check the watertrap for water or occlusion. Empty the watertrap, or replace the watertrap if necessary.
4. Check the gas outlet and the exhaust tube for any occlusion.
If the message does not disappear, it is probably the module fault. Contact the service personnel in this case.
NOTE
For the physiological and technical alarm messages, see Appendix DAlarm Messages.
