RTD connection are shown in Figure 2-6, with the compensating lead
connected to terminal 4. For two-wire RTD inputs, terminals 4 and 5
should be linked. The three-wire RTD offers the capability of lead
resistance compensation provided that the three leads are of same
gauge and equal length.

Two-wire RTD should be avoided, if possible, for the purpose of accuracy.
A 0.4 ohm lead resistance of a two-wire RTD will produce 1 degree C
temperature error.
