FIELD: measurement equipment. ^ SUBSTANCE: invention is related to instrumentation and control equipment, automatics and industrial electronics, and may be used to detect parametres of three-element dipoles or parametres of detectors with three-element equivalent circuit. According to invention, bridge metre of dipole parametres comprises serially joined generator of feeding complex electric signal, bridge circuit and zero indicator. Peculiarity of bridge metre of dipole parametres consists in introduction of additional second resistor and second capacitor into dipole with balancing elements, included into bridge circuit, and additional components are connected to each other as parallel, and are also connected parallel to available circuit from serially connected first capacitor and first resistor. Functional elements of dipole with balancing elements are adjustable, and functional elements of measurement item dipole are used as sought for three parametres - the first and second resistors and the first reservoir. ^ EFFECT: separate balancing of bridge circuit in process of single-time adjustment of all three parametres, which simplifies performance of measurements. ^ 1 dwg |
