FIELD: electrical instrumentation engineering. SUBSTANCE: device depends for its operation on measuring parameters of double-pole multicomponent circuit using integral characteristics of transient component in measuring circuit when square pulse is applied from reference-voltage source. Device enables measurement of parameters in both RC- and RLC-type double-pole multicomponent circuits in which case it may be both aperiodic and decaying-wave transient process. Integration operation enables reducing impact of random error component and transient component makes it possible to eliminate effect of measuring-channel additive error on measurement results. More universal measuring instruments and transducers for measuring parameters of double-pole multicomponent circuits can be built around proposed invention. EFFECT: enlarged functional capabilities of device. 1 cl, 5 dwg, 1 tbl
