When the HART Communicator
is connected to the transmitter
and turned on, the first screen
that is seen by the user is the root
menu screen. If the transmitter is
configured as Level Only or Level
plus Temperature, the screen to
the left shows the information
displayed to the user.
However if the transmitter is
configured as Level plus Interface
or Level plus Interface plus
Temperature and Interface has
been selected as the Primary
Variable (Interface controls the
current output), the screen to
the left shows the information
displayed to the user.
When the user selects the top
menu entry on the root menu,
Device setup, by using the right
arrow, the next screen displays
five menu selections available to
the user. Each of these menu
selections will provide detailed
information about a specific portion
of the transmitter as detailed in the
following sections.
If the user selects the Process
variables menu from the Device
setup screen, the next screen
displays the current values for all
of the dynamic variables. If the
transmitter is not configured for
Interface, the entry “Interf” is not
displayed. If the transmitter is not
configured for temperature, the
entry “Temper” is not displayed.
If the user selects Diag/Service
menu from the Device setup
screen, the next screen displays
further menu selections to the user.
These selections will be presented
in more detail in the section titled

If the user selects Basic setup from
the Device setup screen, the next
screen has a mixture of further
menu selections and detailed
information. This screen displays
the name of the variable that is
controlling the output current (PV),
the tag and the Alarm type. In
addition this screen presents the
procedure to select the Primary
variable (PV) if the transmitter is
configured with both Level and
Interface. It also displays the
menu that will allow the user to
change the range values. The

and perform the re-ranging of the
transmitter will be presented in
more detail in the section titled

the list the only way to end this
series of screens is to select EXIT
