FIELD: physics.
SUBSTANCE: device has a base, a holder made in form of a threaded pair, a bolt head joined to the spindle of the test nut wrench and to the nut through a torque sensor which interacts with the base. The torque sensor is connected to a monitoring unit which has an analogue-to-digital converter, a first digital comparator, a first memory register, a digital display, an AND logic element and an amplifier. The device is also fitted with a computing device, second and third digital comparators, second and third memory registers, a pulse counter, a memory unit, an analogue comparator, a logic inverter and a trigger circuit.
EFFECT: broader functional capabilities through automatic detection of faulty items.
