Quick Start Guide
Transmitter primary variable units (P012)
This selects alternative display units for the HART Primary Variable (PV), which are
then reported to a HART Master Device such as a Rosemount 3490 Series Control Unit.
Note
Selecting alternative display units does not automatically re-scale the PV value.

Transmitter tank shape / non-linear profile (P011)
This selects the shape of a tank or an open channel, and establishes the linear or
non-linear relationship between the live liquid level (height) and the process value
(PV) derived from that level. The transmitter is pre-programmed with popular profiles
that are mathematical formulas to convert a linear level reading to a flow or
volumetric process value (PV). The Current Output is then driven by the flow or
volumetric PV.
Note
Select "Linear" if the process value (PV) is a level measurement.
