Wire the RTD Sensors

In an RTD sensor, the sensing element is always connected between two wires of
different colors. Wires of the same color are shorted and form the compensation
leads. Measuring resistance between these wires confirms the position of sensing
element and compensation elements. Compensation elements will always show
0 ohms.
