Viatran DL Series Analog Input Process Meter Instruction Manual

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.
Additionally, the meter can be set up to display the analog input on the
main display and the Modbus input on the second display. The relays
and analog output can be programmed to operate from the Modbus PV
input.
