3.11.2.10 RTD/mA input connection
RTD inputs can be used with 2-wire or 3-wire connection with common ground.
When using the 3-wire connection, it is important that all three wires connecting
the sensor are symmetrical, that is, the wires are of the same type and length, hence
the wire resistance is automatically compensated.
