Abstract The article examines the possibility of determining the parameters of multi-element bi-pole using the author’s method of aggregate measurements. Mathematical modeling of measuring circuits is performed, the random error of the results of measurements of parameters of a four-element bi-pole by the Monte Carlo method is estimated and determination result of the methodological and random components of the measurement errors of parameters of circuit elements is presented. The relevance of the application of the combined method of research with measurements in steady-state and transient modes for determining the moisture content of agricultural products is justified. The reduction of the resulting methodological error and the possibility of reducing the number of analog-to-digital transformations without deteriorating the target accuracy are proved.
