摘要
FIELD: measurement equipment.;SUBSTANCE: invention relates to technological devices and can be used together with a measuring instrument (ohmmeter) at control of feed circuits of an electrotechnical system of an item during its assembly for compliance with requirements of technical documentation - absence of breaks, short circuits, and other incompliances with technical requirements. The proposed device includes three input circuits and two output circuits, a switch for three positions and four directions, a diode and two low-ohmic resistors R1 and R2 and electrical connections between elements of the device, which provide safe quality control of feed circuits of the electrotechnical system of the item during its assembly from the point of view of electrical actions.;EFFECT: increasing productivity due to reduction of the number of check measurements, exclusion of influence of interference and errors of connection of the measuring instrument for reliability of the assembled electrotechnical system of the item, providing objectivity and reliability of control and detection of errors or defects in the assembled electrotechnical system of the item.;2 cl, 1 dwg
