CONTROL-TESTING DEVICE Russian patent published in 2019 - IPC G01R31/02 B60R16/02 G01R31/24 

FIELD: physics.

SUBSTANCE: invention relates to means of monitoring technical condition and can be used for control tests of electric equipment assemblies of ground vehicles with voltage of 12–24 V. Control and verification device comprises parallel direct current source 1 and potentiometer 2 with variable cross-section of winding, positive terminal of which is connected to relay-controller 13 terminal I, slider of potentiometer is connected to housing of relay-regulator through terminal K, rheostat 7, one end of winding of which is connected to negative terminal of source, other end through first ammeter 6 and switch 5 is connected to terminal SH of relay-controller, between terminal B of the relay-controller and terminal K there connected in series are second ammeter 10 and accumulator battery 8, between terminal K and terminal 3 lamp 4 is connected, the potentiometer is made three-sectional, its middle section R2 contains thin wire, other sections R1 and R3 are made with thick wire with possibility of control of charge and discharge currents of accumulator battery.

EFFECT: technical result is aimed at enlarging the range of inspected electrical equipment, reducing operating costs and increasing efficiency.
