3.1 - Display Indications

Initially, after the power is first turned on, the flow meter model number is shown in
the first line of the display and the revisions for EPROM table and firmware in the
second line. Subsequently the actual process information is displayed. The
instantaneous flow rate is displayed on the first line in percent or in direct reading
units with flow alarm status indication. For flow meters without RTD option, the
main totalizer value, up to 9 digits (including decimal), is displayed in the second
line with its corresponding units.

For flow meters with RTD option, the temperature reading value in deg C, is
displayed in the second line with temperature alarm status indication. This display
is designated as process information (PI) screen throughout the remainder of this
manual.

The temperature value (applicable for RTD option only) in deg F can be displayed
in the PI screen by pressing the ENT pushbutton. The temperature indication can
be switched from deg C to deg F and back by pressing ENT push button.
