The Rosemount 2051 manual describes how to use HART to
configure the LRV (Lower RangeValue) and the URV (Upper
Range Value) which define the range represented by the 4.0
and 20.0mA output in the section "Rerange with a HART
Communicator or AMS Device Manager Only".

Using the pushbuttons requires a pressure source (which can
be liquid in the tank, or a calibration source) as described
in section "Rerange with a Pressure Input Source and a HART
Communicator or AMS Device Manager"

But if you don't answer the questions I posed in the
previous post, then you won't know what values to use for
LRV and URV.
