CHIAVE TER.COMP. CONTROLLI VALORI
MAR 1(+) - 3(-) tensione d'alimentazione 4,5 - 5 volt
MAR 2(S) - 3(-) segnale d'uscita 0,5 - 5 volt
    * Segnale uscita EGR = senza depressione 1,2volt
                                         con depressione 4,3volt
  … preferibile usare per  controllare il  segnale in uscita dei potenziometri, un
  multimetro con strumento a lancetta, se non  si  dispone di  un  oscilloscopio,
  in quanto i seghettamenti sul segnale, causa principale di malfunzionamento,
  sono piŁ facilmente individuabili.
