Description: For study weight measuring system unceasing dose loose material by means of package of the applied programs is received it was received optimum of plan full factorial experiment by cost of the realization and mathematical models, describing dependency of relative errors of the measurement from essential factor. The optimum models of its functioning are determined. For study of errors such instrument as device of the checking quality of dielectric material, curl current converter of the thickness dielectric covering, noncontact meter of the direct current and density of the current are received optimum plans of the experiment by price expenses. Benchmark analysis of got plan was carried out.
