BRIDGE METER OF TWO-TERMINAL CIRCUIT PARAMETERS Russian patent published in 2017 - IPC G01R17/10 

FIELD: measuring equipment.

SUBSTANCE: bridge meter of two-terminal circuit parameters contains the series connected generator of the supplying complex electrical signal, the bridge circuit and zero indicator. The generator consists of the impulse sequences shapers of rectangular shape, linearly changing, quadratic and cubic, from the switching unit, power amplifier and the synchronization unit. The bridge circuit consists of two branches. The first branch is formed by series connected the first, the second and the third resistors. Parallely to the second and the third resistors circuits the inductive coil is connected. The second bridge branch is formed by the single capacitor and terminals connected in series for the measurement object two-terminal circuits connecting. At that seven additional resistors, the additional inductive coil are introduced and the elements switching on is changed. Parallely to the second available resistor the series circuit is connected, formed by the first additional resistor and the inductive coil. The second and the third additional resistors, connected in series, are connected to it parallely. The fourth additional resistor and the additional inductive coil, connected in series, are connected parallely to the second additional resistor. The fifth additional resistor is connected parallely to the latter, and as well as the series connected the sixth and the seventh additional resistors.

EFFECT: bridge circuit separate balancing by only adjustable resistors.
