FIELD: electrical engineering. SUBSTANCE: device has generator 1 of sequences of rectangular pulses, linearly-varying, square and cubical waveforms, electric bridge 2, and balance indicator 4. The first arm of electric bridge is formed by series-connected measurement object 3 and inductance coil 8. Object of measurement has series-connected capacitor 5 and resistor 6 in parallel to which inductance coil 7 is connected. The second arm of electric bridge is formed by series-connected inductance coil 9, resistors 10 and 11 and inductance coil 12. Series-connected capacitor 13 and resistors 14 and 15 are connected in parallel to coil 12. Resistor 16 is connected in parallel to series-connected inductance coil 9 and resistors 10 and 11. In addition, resistor 17 is connected between common lead of capacitor 5, inductance coils 7 and 9 and resistor 16 which is first apex of diagonally opposite pair of terminals of bridge power supply, and common lead of resistors 14 and 15. Device uses only adjustable resistors as balancing elements. EFFECT: reduced mass and dimensions. 2 dwg
