Should I use 2 or 4 wires to attach my sensor to the instrument?
Using 4 wires to attach a sensor to any temperature instrument is always recommended. If you use 2-wire leads, the resistance of the leads adds to the actual sensor value and induces errors into the measurement. The use of 4 wires eliminates any error induced from the resistance of the leads.
