Fresh Gas Sensor
S1 places a short across PT3 during Auto Zero this allows the differential pressure to equalise
PT5 is the Patient Pressure gauge
PT2 measures the Drive Gas Flow via the sensor in the main pneumatic block
PT4 measures the Drive Gas Pressure via a port in the main pneumatic block
PT1 measures the Fresh Gas Flow via a sensor in the common gas outlet of the Anaesthesia system
PT3 measures the Patient Gas Flow via a sensor in the Patient circuit
