METER OPERATION
The meter is capable of accepting current (0-20 mA, 4-20 mA) and
voltage signals (0-5 V, 1-5 V, 0-10 V,
 10 V) and displaying these
signals in engineering units from -99999 to 999999 (
e.g. a 4-20 mA
signal could be displayed as -50.000 to 50.000).
The dual-line display can be customized by the user to operate in such
a way as to satisfy a specific application. Typically the main display is
used for the process variable; while the second display is used for
engineering units, custom legend, or set point indication.
The analog input can be scaled to display the process in two different
scales; for example: with
d-SCAL enabled, the main display could
indicate level in feet and the second display could indicate the volume in
gallons.
