This paper described the theoretical basis of extreme value orientation in detail, which is used to examine the dimension of hole and axle with double point one coordinate measure instrument, and it's quality and feature and calculation method of survey error on dimension, which is caused by turn back point error. The paper also provide a practical chart, which is used to revise at the same time also introduced the study method which is designed by author.
