Pt100 second-line how connection between the heating resistance and display instrument?

In general, the heat resistance of the three lines 1, 2, 3 terminal.

if display instrument have wiring diagram, wiring methods see illustration.

if there is no wiring diagram or lost the wiring diagram, wiring according to the following method:

the thermal resistance of three wire, if there are two same color, wiring connected the two wires of the same colour when 2 and 3 terminal, a terminal 1, after turning on the power supply if the display is not normal, According to maximum or minimum) , the no. 1 on the wire and terminal 3 terminal wiring change.

if three wire color each are not identical, there must be one is red, when wiring the red wire to terminal 1, the two remaining wire to terminal 2 and 3, after turning on the power supply if the display is not normal, According to maximum or minimum) , the no. 1 on the wire and terminal 3 terminal wiring change.
