Method for Evaluating Angle Measurement Uncertainty of Gun Clinometer

doi:10.3969/j.issn.1000-1093.2017.04.025

Abstract

Abstract: In order to facilitate understanding, exchange and comparison, a clinometer is asked to provide an uncertainty in the competition task. In the actual measurement, the evaluation of class A is difficult when the sample size is small.A laboratory calibration process is proposed to approximate the actual measurement process. The historical calibration data and linear regression are used to establish a class A evaluation method based on statistical process control technology. The method is proved to be feasible by using the historical calibration data of a certain type of clinometer and the MATLAB tool. The GUM me- thod is used to obtain the extended uncertainty curve at any angle. This conclusion is verified by Monte Carlo method. Key
