Mindray A9 Service Manual

5-2
5.2 System Check
Three system check modes are available: power-on self-test, leak test, and vaporizer test (for A9).
NOTE
 Both the leak test and vaporizer test are used to check for leakage in the backend
circuit of the flowmeter. The difference lies in whether the anesthesia machine is
equipped with a vaporizer. During the system check, the anesthesia machine
automatically performs detection and selection. You can also manually select the
corresponding test on the standby screen. If you select the vaporizer test but no
electronic vaporizer is loaded, the test may fail.
