Abstract

Testeur destiné à être connecté au système de commande électrique d'un moteur à combustion interne pour surveiller une pluralité de signaux électriques représentant des paramètres de ce système de commande et procurer une indication des signaux surveillés défaillants et du premier qui l'a été. Testeur comprenant un circuit pour échantillonner la pluralité de signaux électriques connecté à un circuit pour traiter les signaux échantillonnés avec une pluralité de valeurs de référence et délivrer une même pluralité de signaux de sortie, chacun de ces derniers contenant une information indiquant si le signal échantillonné correspondant est défaillant; un premier circuit indicateur connecté au circuit de traitement est destiné à indiquer les résultats défavorables du traitement et à identifier lequel des signaux électriques est défaillant; et un second circuit indicateur connecté au circuit de traitement et destiné à indiquer lequel des signaux électriques a été le premier à présenter une défaillance.A tester for connection to the electrical control system of an internal combustion engine to monitor a plurality of electrical signals representing parameters of that control system and to provide an indication of which monitored signals failed and which first failed. Tester comprising a circuit for sampling the plurality of electrical signals connected to a circuit for processing the sampled signals with a plurality of reference values and providing a same plurality of output signals, each of the latter containing information indicating whether the corresponding sampled signal is faulty; a first indicator circuit connected to the processing circuit is for indicating the unfavorable results of the processing and identifying which of the electrical signals is faulty; and a second indicator circuit connected to the processing circuit and for indicating which of the electrical signals was the first to fail.
