3.16  PRESSURE and SENSOR READING allocation 

 
Example of PRESSURE and SENSOR READING allocation: 

 

 

 

 
Above picture shows a 2 sensor system. In this configuration sensor 2 covers low range (100 mTorr) and sensor 1 
covers high range (1 Torr). 
Switchover between sensors is done automatically according to «Pressure control operation with 2 sensors».
