AG Calibration
Tools required:
Gas cylinder with a certain standard gas or standard gas mixture. Gas concentration
should meet the following requirements respectively: AA≥1.5%, CO2≥1.5%, N2O≥40%,
O2≥40%, of which AA represents an anaesthetic agent. The gas concentration accuracy
should have a tolerance as follows: AA±0.15%, CO2±0.1%, N2O±1%, O2±1%.

NOTE
When calibrating a particular gas in a mixture, only the concentration of the gas to
be calibrated needs to meet the requirements.
Handle the gas cylinder by following the instructions on the gas cylinder(s).
Follow this procedure to perform the AG calibration:
1. Select [Main Menu]→[Maintenance >>]→[User Maintenance >>]→enter the
required password→[Module Maintenance >>]→[Calibrate AG >>]..
2. Check the airway and make sure that there are no occlusions or leaks.
Vent the sampling tubing to the air and check if the [Current FlowRate] and
[SetFlowRate] are approximately the same. If the deviation is great, it indicates
that there is an occlusion in the tubing. Check the tubing for an occlusion.
Perform a leakage test to make sure that the airway has no leakage.
3. Connect the test system as follows:
4. Open the relief valve and vent a certain standard gas or gas mixture and make sure that
there is an excess gas flow through the T-shape connector to air. And wait for at least 30
seconds until the gas reading stable.
