mV field: signal is scaled
to mV.
Gain : User gain. It is
scaled as (User
gain)/(Factory gain).

Sample Flow is calculated from differential pressure and adjusted by the module. Zero value as
measured during initialization when the pump is off. Gain : sample flow measurement can
be calibrated by adjusting the gain.
Ambient Ambient pressure is measured continuously. Amb-Work : ambient pressure - sampling
system internal pressure.
