The paper considers an effective approach to scientific and practical problems of improving the accuracy of primary electrical transducers. We have analyzed the application of test experiments with non-dismantling control in working conditions with the use of relation and difference correction operators. Owing to the devised methods of minimizing dynamic measurement errors for transducers with non-linear converting function we managed to decrease the dynamic measurement error by 5.0 % from the current analogues. We have estimated the measurement errors for the exponential input signal and researched functional correction operators resulting from nonlinear indirect measurements. The devised engineering method for determining the parameters of test control systems allows solving the problems of synthesis and analysis of the latter: obtaining the necessary amount of ADC bits with the criterion of specified accuracy of measurements, or solving an inverse, in fact a more common, problem and calculating the system accuracy for a specified ADC capacity.
