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.

RTD connection are shown in Figure 2.6, with the compensating lead connected to
terminal 9. For two-wire RTD inputs, terminals 9 and 10 should be linked. The
three-wire RTD offers the capability of lead resistance compensation provided that the
three leads should be of same gauge and equal length.
