NOTE
" When testing a particular gas in a mixture, only the concentration of the gas to be
tested needs to meet the requirements.
" Handle the gas cylinder by following the instructions on the gas cylinder.
Follow this procedure to perform the test:
1. Plug the AG module into the module rack.
2. Wait 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. Open the relief valve and vent a standard gas 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.
6. Check that the concentration of each composition meets the specification stated in the
Operator's Manual.
