| Abstract: | In this paper,the evaluation course of DC gain and offset of linear measurement system using the least square method is described,the uncertainty analysis of the evaluation is discussed,and in the meantime an example of evaluation and analysis is introduced in detail. The course and results can be used in the uncertainty analysis of some measurement standard or the uncertainty ana1ysis of gain and offset themselves. |
