HART device is not actually fitted.
The Secondary and Tertiary values of a P1 pressure HART device are
not converted, and they are simply translated from the HART device to
the FlexConn environment.

P3 Pressure

The FCI-HT software only accepts the Primary Value of a P3 pressure
HART device in SI units kilo Pascals (kPa).
☛
Make sure the P3 pressure HART device is configured to output data
in kilo Pascals (kPa). If not, correctly configure as yet, by using an
appropriate HART configuration tool.

NOTE: The Secondary and Tertiary values of a P3 pressure HART
device may be any units.
The PV of the P3 pressure HART device is read and converted into SI
Units Pascals (Pa) within the FlexConn function PV.
