Abstract

Cette invention concerne un circuit de mise sous tension d'une électrode de cellule d'essai biométrique, électrode qui est en contact avec une paire de contacts espacés lorsqu'elle est bien introduite dans un connecteur femelle. Le circuit comprend une source de tension d'excitation et un amplificateur dont une des entrées est connectée à la source d'excitation. Un circuit de commutation est établi entre l'amplificateur et un des deux contacts espacés ci-dessus, ledit circuit affichant une impédance. Un circuit de retour est établi entre le second des contacts espacés et une autre entrée de l'amplificateur pour renvoyer à celui-ci la tension au second contact. Ce retour d'information a pour objet de maintenir la sortie de l'amplificateur à un niveau permettant de compenser les pertes par impédance dans le circuit de commutation. Le circuit de retour permet de varier la sortie de l'amplificateur de manière à maintenir l'égalité entre la tension appliquée à l'électrode et celle de la source d'excitation. Un autre circuit est raccordé au circuit de retour pour détecter un circuit ouvert ou une impédance élevée entre les deux contacts espacés.
