2.1.1.11 Altitude comp. (marker #11a-11b of image 2.1.1)
AMBIENT PRESSURE (mmHg) - Allows the operator to set the pressure at which the Machine case will be operating.(default is 760.00 mmHg based on
0 ft Altitude 1976 U.S. Standard Atmosphere)
AMBIENT TEMP (Kelvin) - Allows the operator to set the temperature at which the machine case will be operating. (default is 288.15 Kelvin based on 0 ft altitude 1976 U.S. Standard Atmosphere)
the operator may setup the system so that actual breathing parameter settings compensate ambient flow rates to standard flow rates. Whereby all measurements taken regardless of altitude are referenced in standard flow.
