5.2.3 AG Tests and Calibration
5.2.3.1 Leakage Test
1. Plug the AG module into the module rack.
2. Wait for a minute 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 be displayed.
3. Block the gas inlet for another 60 seconds, Then select [User Maintenance >>]
→
[Maintain AG >>]
→
[Calibrate AG >>] and check that the current flow rate is less than 10 ml/min. If the alarm message does not
disappear, it indicates that the module does not leak.
5.2.3.2 Accuracy Test
Tools required:
Gas cylinder with a certain standard gas (4% Desflurane, 6% CO
2
, 45% N
2
O, Bal O
2
, P/N: 0075-00-0048-01 and flow
regulator P/N: 0119-00-0235). Gas concentration should meet the following requirements : AA ≥ 1.5%, CO
2
≥
1.5%, N
2
O ≥ 40%, O
2
≥ 40%, of which AA represents an anesthetic agent (Des, Sev, Enf, Iso, or Hal). a/c ≤ 0.01 (a is
the gas absolute concentration accuracy; c is the gas concentration)

Appropriate tubing
1. Plug the AG module into the module rack.
2. Wait for at least 10 min and then perform a leakage test to make sure the airway has no leakage.
3. Check if the fan inside the AG module works correctly.
4. Connect the test system as follows:
5. Adjust the relief valve and make sure the flowmeter reading is stable and within 10 and 50 L/min.
6. Check that the concentration of each composition meets the specification stated in the Operator's Manual.
