Variational Method of Calibration of Impedance Meters. Part 1. Basic Assumptions

  • M. N. SurduEmail author

The variational method of increasing the precision of instruments for the measurement of the impedance parameters is considered. The method is based on variations of the coefficients of influence of the sources of an error on the result of measurements. It is shown that each variation of an influence coefficient of a particular source of error is accompanied by a corresponding measurement of the input quantity. A solution of the system of equations that describes these measurements and that makes it possible to obtain an exact result is presented. Devices used for different purposes constructed on the basis of the variational method are described.
