DIMENSIONLESS SENSITIVITY AS THE BASE FOR ESTIMATION OF ERROR OF METERS OF INTEGRAL CHARACTERISTICS

摘要

The new approach for development of determination method of accuracy estimation for meters of integral characteristics is proposed. This method is based on the measurement or determination of dimensionless sensitivity. The dimensionless sensitivity is determined as α(x)=(d(1g y))/(d(1g x))=x/y·(dy)/(dx) (1) For the finite increments of argument and function the expression (1) can be rewritten as: α((x_n+x_(n+1))/2)=(x_(n+1)+x_n)/(x_(n+1)-x_n)·(y_(n+1)-y_n)/(y_(n+1)+y_n) (2) The method can be used for the cases with difficulties for calibration of meters of integral values.
