Изобретение относится к электротехнике и может быть использовано для измерения омического сопротивления различных электрических цепей, находящихся под действием изменяющегося по величине постоянного или выпрямленного тока. Устройство для измерения омических сопротивлений электрических цепей содержит блок управления, источник постоянного или выпрямленного тока силовой цепи, коммутатор, измеряемое сопротивление с клеммами, первый и второй ключи, основной и вспомогательный источники стабилизированного тока и накопительный элемент. Введение в устройство коммутатора и вспомогательного источника стабилизированного тока, а также выполнение накопительного элемента в виде RC-цепи и первого и второго ключей в виде диодов, включенных последовательно с основным и вспомогательным источниками стабилизированного тока в проводящем направлении для токов упомянутых источников позволило существенно расширить функциональные возможности и область применения устройства, а также повысить точность измерения сопротивления контролируемой электрической цепи.The invention relates to electrical engineering and can be used to measure the ohmic resistance of various electrical circuits under the action of varying DC or rectified current. A device for measuring the ohmic resistances of electrical circuits contains a control unit, a source of constant or rectified power circuit current, a switch, a measured resistance with terminals, the first and second keys, the main and auxiliary sources of stabilized current and a storage element. Introduction to the switch device and auxiliary source of stabilized current, as well as the implementation of a storage element in the form of an RC circuit and the first and second keys in the form of diodes connected in series with the main and auxiliary sources of stabilized current in the conducting direction for the currents of the said sources, has significantly expanded the functionality and the scope of the device, as well as improve the accuracy of measuring the resistance of a controlled electrical circuit.
