Structural-algorithmic method for increasing accuracy in rms voltage voltmeters
Viktor Litvikh, Zhanna KosharnaThe paper presents a classification of mathematical models of the conversion characteristics of the measuring channel of measuring instruments. Such models allow the synthesis of two-parameter correction algorithms that significantly reduce not only the additive and multiplicative errors, but also the nonlinearity error. A structural diagram of a root-mean-square voltage voltmeter is proposed, in which the nonlinearity error is reduced by more than an order of magnitude.
