Two-wire RTDs 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 connections are shown in Figure 2.6, with the compensating lead connected to
terminal 19. For two-wire RTD inputs, terminals 19 and 20 should be jumpered. The
three-wire RTD offers the capability of lead resistance compensation provided that the
three leads should be of same gauge and equal length.
