FIELD: measurement equipment.
SUBSTANCE: invention relates to measurement equipment and represents a device to control transition resistance of a sliding contact of electric machines, for instance, rotary transformers, and angle converters. The device comprises an electric motor, a reducer (19) and a sensor of angular position (18), to which the inspected electric machine is connected. The control unit (CU, 21) comprises a source of power supply, a T-trigger, an "AND" circuit, a relay (24) with a winding (25) and a normally closed contact (26), a tumbler "START". The measurement circuit of the device comprises a controlled stabilised DC source, a key, a controlled resistor, two amplifiers, a comparator, an inverter, a multivibrator, two "AND" circuits, two counters, two registers, a resistance meter (16), a computer (15).
EFFECT: increased functional possibilities and accuracy of control of electric machines and angle converters.
