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 upper display is
used for the process variable; while the lower display is used for
engineering units, custom legend, total, grand total, or set point
indication.
The meter can be set up to display the analog input on the upper
display and the Modbus input on the lower display. The relays and
analog output can be programmed to operate from the Modbus PV
input.
