Abstract

Inventia se refera la o metoda pentru masurarea abaterii relative a rezistentelor cu convertor analog numeric cu dubla integrare. într-un prim proces de conversie analog numerica se stabileste o rezistenta reglabila la valoarea fata de care se masoara abaterea relativa. Al doilea proces de conversie analog numerica consta în integrarea unui curent functie de rezistenta reglata în primul proces si apoi integrarea unui curent functie de rezistenta de masurat pe durata careia un numarator numara însens invers (de la capacitatea maxima) impulsuri date de un generator, rezultînd un numar functie liniara de abaterea relativa a rezistentei de masurat fata de valoarea reglata, numar indicat de un dispozitiv de afisare. Aparatul conform inventiei p ermite masurarea si afisarea abaterii relative a rezistentelor si este utilizabil în industria electronica.The invention relates to a method for measuring the relative deviation of resistors with numerical analogue converter with dual integration. In a first numerical analog conversion process, an adjustable resistance is established at the value against which the relative offset is measured. The second numerical analog conversion process consists in integrating a current resistive function regulated in the first process and then integrating a current measuring resistance function during which a counter counts the inverse (from the maximum capacitance) pulses given by a generator, resulting in a linear function number of the relative deviation of the measured resistance from the set value, a number indicated by a display device. The apparatus according to the invention allows the measurement and display of relative resistance deviations and is usable in the electronics industry.
