The AG module can identify two anesthetic agents automatically. When the proportion of primary and
secondary anesthetic agents in the mixture changes, the AG module can distinguish between them according to
their contributions to the MAC value. Then primary and secondary anesthetic agents will be exchanged for
display.
19.11 Performing AG Leakage Test
The AG leakage test is required every time before the AG measurement. To perform the AG leakage test, follow
this procedure:
1. Plug the AG module into the module rack.
2. Wait for about one minute until the AG module warms up. Completely block the gas inlet of the AG
module. Then the alarm message “
AG Airway Occluded
” will appear on the screen.
3. Block the gas inlet for another one minute.
4. Select the

select .
5. Select the
Module
tab
→
AG
tab.
6. Check that the current flow rate is less than 10ml/min, and the alarm message “
AG Airway Occluded
” does
not disappear.
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.
19.12 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.
19.13 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.
