【Abstract】 A calibrating standard of three points is being used for verificating the synthetical accuracy of the 2-D measuring instrument, when the x₁ and x₂ been put in, and the output y₁ and y₂ would be obtained. Then we can obtain the synthetical deviation of the ordinate and abscissa from closed error equation.更多还原
