Operation
The meter is capable of accepting a variety of
thermocouples and RTDs.
The dual-line display can be customized by the user to
operate in such a way as to satisfy a specific
application. Typically, display line 1 is used for the
process variable; while line 2 is used engineering units,
custom legend, or set point indication.
Additionally, the meter can be set up to display the
thermocouple or RTD input on line 1 and the Modbus
input on line 2. The relays and analog output can be
programmed to operate from the Modbus PV input.
