FIELD: measuring equipment. SUBSTANCE: method and corresponding device enable simultaneous measurement of active and reactive components of impedance, for example of two-terminal networks having electromotive force between terminals which is constant or slowly variable in time, as well as of objects containing electrolytes. Device circuit includes generator, measuring circuit containing impedance being measured, filter, controlled integrator, and control pulse forming unit. EFFECT: enhanced measurement speed. 2 cl, 6 dwg
