According to the literature introduction of calculation formula and measurement methods of centroidal deviation,the accurate error formula was derived. Based on the error formula,the precision contrast of two methods was given. In order to reduce errors,reasonable structure and the improvement plan of the test instrument were put forward. It is pointed out that some conclusions of literature lacks theoretical evidence,should not use as the choice of test method and the basis of precision contrast.
