Abstract

Inventia se refera la tehnica de masurari si poate fi utilizata pentru masurarea cu precizie înalta a rezistentei.Ohmmetrul contine doua cleme (3, 4) pentru conectarea obiectului masurat, un rezistor (2) conectat cu un pol la prima clema (3), o sursa de curent continuu (1), la o borna a careia este conectat cel de-al doilea pol al rezistorului (2), un convertor (5) de rezistenta negativa, dotat cu o intrare de reglare a rezistentei reproduse si cu doua iesiri, una fiind conectata la cea de-a doua clema (4), iar cea de-a doua - la borna a doua a sursei de curent (1), un comparator (6) de tensiune, conectat cu o intrare la prima clema (3), iar cu cea de-a doua - la punctul comun al convertorului (5) si sursei de curent (1). Ohmmetrul mai contine un indicator de tensiune (7), conectat cu intrarea la iesirea comparatorului (6).
