Verifici cu un multimetru rezistenţa  senzorului , ar trebui să fie în jur de 100 ohmi între cele două fire de culoare roşie .  Acestea le conectezi la bornele A şi B ale controlerului .  Firul alb al senzorului se foloseşte doar la lungimi mari ale circuitului ( senzor departe de controler conectat cu cablu lung )  , unde rezistenţa buclei ar putea influenţa temperatura măsurată .
