Abstract:
This paper presents a method for calculating the current linearity of precursor instrument. By using the least square method to process the pipe inclinometer linearity error detection data, the calculation methods of this paper establish an unary linear regression equation, and conduct the significance analysis. At the same time, based on the linearity detection data of the pipe inclinometer linearity station, this paper determines the rationality of the calculation results of the linearity error based on the Bessel method after comparing and analyzing the error of four standard uncertainty calculation methods.This calculation method can reflect the linearity of the precursor instrument more comprehensively, which is of great significance to the performance evaluation of the instrument.
