Abstract

The invention relates to the direct current electrical resistance measuring devices and to methods for calibration of electrical resistance measures.The method for calibration of electrical resistance measures consists in that it is balanced a four-armed electrical resistance measuring bridge, into an arm of which is connected a standard measure of electrical resistance, by modification of the variable resistance of one arm of the measuring bridge, at the same time the resistance of the transfer measure of the other arm possesses a preset value. Afterwards, the standard measure is substituted by the measure of electrical resistance for calibration, it is modified the resistance value of the transfer measure and the bridge is repeatedly balanced by modification of the variable resistance.The bridge for calibration of electrical resistance measures comprises two standard arms (1, 4), into the first (1) being connected the standard measure Rs, with the possibility of further substitution by the resistance measure for calibration Rx, and into the second (4) a variable resistance Rv for bridge balancing, and two relation arms (2, 3), into the first (2) being connected a resistance-tare Rt and into the second (3) an electrical resistance transfer measure Rtm. Between those two pairs of bridge arms it is connected a null indicator (5), the bridge being connected to a power supply (6).
