-field: signal is scaled to mV,
Gain
: User gain. It is scaled as (User gain)/(Factory gain).
ID
Shows the identified agent.
ID unrel.
The shown value tells how
unreliable
the identification is. With pure agent the value is normally <
50.
Sample Flow
Sample Flow
is calculated from differential pressure and is 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
: ambient pressure is measured every 30 min.
Amb-Work
: ambient pressure - sampling
system internal pressure.
