BRIDGE METER OF DIPOLE PARAMETERS Russian patent published in 2015 - IPC G01R17/10 

FIELD: measurement equipment.

SUBSTANCE: invention relates to metrology and may be used to control and determine dipole parameters. A bridge meter of dipole parameters comprises a generator of feed pulses, a four-arm bridge circuit and a zero indicator. The bridge circuit comprises two branches, the first of which comprises two serially connected resistors, the common point of which forms the first outlet of the bridge circuit. The second circuit comprises serially connected resistor and multi-element dipole, the common outlet of which creates the second outlet of the bridge circuit. The bridge meter includes an additional inductance coil and four additional resistors, an additional inductance coil is included into the multi-element dipole of the second bridge branch between the free outlet of the second resistor and "earth", the first additional resistor is connected in parallel to the additional inductance coil, the second additional resistor is connected between free outlet of the first resistor and the second outlet of the output of the four-arm bridge circuit, the third additional resistor is connected between the common output of the second additional and first resistors, and a non-grounded terminal for connection of a dipole of a measurement object, the fourth additional resistor is connected between the second outlet of the output of the four-arm bridge circuit and a non-grounded terminal to connect the dipole of the measurement object.

EFFECT: improved accuracy of measurements.
