If the calibration is finished successfully, the message [Calibration Completed!] is
displayed in the [Calibrate CO
2
] menu. If the calibration failed, the message [Calibration
Failed!] is displayed. In this case, perform another calibration.
3.2.4 AG Tests
AG Leakage Test
The AG leakage test is required every time before the AG measurement. Follow this
procedure to perform the test:
1. Plug the AG module into the module rack.
2. Wait for more than10mins until the AG module warmup is finished and then use your
hand or other objects to completely block the gas inlet of the AG module. An alarm
message [AG Airway Occluded] will appear on the screen.
3.
Block the gas inlet for another 30 s. Select [Main Menu]→[Maintenance >>]→[User
Maintenance >>]→enter the required password→Module Maintenance >>]→
[Calibrate AG >>].
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 or greater, it indicates that the
module leaks. Perform the leakage test again. If the problem remains, contact your service
personnel for help.
AG Accuracy Test
Tools required:
! Gas cylinder with 100% O
2
and/or a certain standard gas (such as 6±0.05% CO
2
, Bal N
2
),
or standard gas mixture (such as 5±0.03% CO
2
, 1.5±0.15% ISO, 45±0.23% O
2
bal N
2
O).
! Gas concentration should meet the following requirements respectively: AA≥1.5%,
CO
2
≥1.5%, N
2
O≥40%, O
2
≥40%, of which AA represents an anaesthetic agent. The gas
concentration accuracy should have a tolerance as follows: AA±0.15%, CO
2
±0.1%,
N
