3.2.4 AG Tests 
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 
[AC 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. 
 
Accuracy Test 
Tools required: 
  Gas cylinder with a certain standard gas (such as 6 ± 0.05% CO
2
, Bal N
2
), or standard 
gas mixture. 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)   
  T-shape connector   
  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: 
 
 
 
Monitor 
Gas cylinder 
Open to the air 
Relief valve 
Tubing
