METHOD OF MEASURING RESISTANCE, INDUCTANCE AND CAPACITANCE AND DEVICES FOR REALISING SAID METHOD Russian patent published in 2010 - IPC G01R27/26 

FIELD: physics.

SUBSTANCE: three successive cycles are made for measuring oscillation frequency at different configuration of a frequency sensitive circuit. In the fist cycle, a measured value is created, where Z_st1 is a first standard passive electric element which is homogenous with the measured electric element. In the second cycle, a measured value is created, where Z_st2 is a second standard passive electric element which is homogenous with the measured electric element. In the third conversion cycle, a measured value is created, where Z_st3 is third standard passive electric element which is homogenous with the measured electric element. The unknown value of the measured electric element is determined using the formula where N₁, N₂, N₃ are results of the first, second and third conversion cycles respectively.

EFFECT: higher measurement accuracy.
