Abstract

Inventia se refera la dispozitivele de masurare a rezistentei electrice de curent continuu si la metodele de etalonare a masurilor de rezistenta electrica. Metoda de etalonare a masurilor de rezistenta electrica consta in aceea ca se echilibreaza o punte de masurare a rezistentei electrice cu patru brate, intr-un brat al careia este conectata o masura-etalon de rezistenta electrica, prin modificarea rezistentei variabile a unuia dintre bratele puntii, totodata rezistenta masurii de transfer a altui brat poseda o valoare prestabilita. Dupa care se substituie masura-etalon cu masura de rezistenta electrica pentru etalonare, se modifica valoarea rezistentei masurii de transfer si puntea se echilibreaza repetat prin modificarea rezistentei variabile. Puntea pentru etalonarea masurilor de rezistenta electrica contine doua brate de comparare (1, 4), in primul (1) fiind conectata masura-etalon Re, cu posibilitatea substituirii ulterioare cu masura de rezistenta pentru etalonare Rx, iar in al doilea (4) o rezistenta variabila Rv pentru echilibrarea puntii, si doua brate de raport (2, 3), in primul (2) fiind conectata o rezistenta-dara Rd, iar in al doilea (3) o masura de transfer a rezistentei electrice Rmt. Intre cele doua perechi de brate ale puntii este conectat un nul-indicator (5), puntea fiind conectata la o sursa de alimentare (6).The invention relates to the devices for measuring the electrical resistance of DC and to the methods of calibrating the measures of electrical resistance. The method of calibrating the electrical resistance measures consists in balancing an electrical resistance measuring bridge with four arms, in an arm to which an electrical resistance measurement standard is connected, by modifying the variable resistance of one of the axle arms. , at the same time, the resistance of the transfer measure of another arm has a default value. After which the standard measure is replaced by the electrical resistance measure for calibration, the value of the transfer measure resistance is changed and the bridge is repeatedly balanced by changing the variable resistance. The bridge for calibrating the electrical resistance measures contains two comparison arms (1, 4), in the first (1) the measurement standard Re is connected, with the possibility of subsequent substitution with the resistance measure for calibration Rx, and in the second (4) a variable resistance Rv for balancing the bridge, and two ratio arms (2, 3), in the first (2) a resistor is connected by Rd, and in the second (3) a measure of transfer of the electrical resistance Rmt. Between the two pairs of arms of the bridge is connected a zero-indicator (5), the bridge being connected to a power supply (6).
