The Analog output source can be any internal or external
analog signal.
The Analog output range is the engineering range of the
output signal – see below.
The 'Engineering low' and 'Engineering high' settings allow
the engineering values corresponding to the 'Electrical low'
and 'Electrical high' values to be set.
The 'Electrical low' and 'Electrical high' values are the
minimum and maximum values of the current output, in
Electrical units. Range: 0 to 21mA.

Refer to APPENDIX 2 for information on using the Modbus
link.
Set according to the number of transmission wires
connected to the instrument: 4-wire, 2-wire.
Set the Baud rate used by the host system: 1200, 2400,
4800, 9600, 19200, 38400, 115200.
Set the Parity used by the host system: None, Odd, Even.
Set a unique Modbus Address that allows the host system to
identify the instrument on a Modbus link.
Note. Maximum 31 slaves per loop.
