3.4.1 Thermistors
Thermistors are resistive devices and do not have polarity. Connect one lead to the input terminal of
the desired input and the second lead to a common terminal. Quest recommends using shielded and
stranded cable for all analog sensors. Connect the shield of the cable to chassis ground on the MP1. Cut
the drain wire and isolate the shield at the sensor end of the cable.
