The paper considers the research materials obtained during the research work on the topic "Creation of a scientific and methodological basis for improving the accuracy of conductometric measurements". The main scientific and technical results are aimed at the further development of the theory of measuring the imitation of conductors with an ionic conductivity type and consists in the development of three mathematical models for calculating errors built on the basis of chain-field problems and allowing to take into account nonlinearity of power lines of current density predetermined: changes the nature of the operating current, in particular the influence of the vector magnetic potential, the presence and boundary conditions on current and potential electrodes, the real geometry of current electrodes (the presence of openings and conical holes); two methods of constructing balancing bridge measuring circles that provide the invariance of transformation to non-informative parameters of the electric mode, which are commensurable or significantly exceed the informative parameter; two methods for determining the main metrological characteristics of 6-8 decades transformer bridges for measuring resistance sensors.
