Abstract

The accuracy of micro-resistance measurements is an issue of widespread concern in industry. In this paper, we review the methods and main mathematical methods of tiny resistance measurement, firstly, we introduce the three basic mathematical knowledge of multiple regression model, the principle of least squares and the calculation of error, then we review the two-wire resistance measurement method and four-wire resistance measurement method. This paper presents a systematic description of the methods and mathematical theories related to the measurement and fitting of tiny resistors to provide a theoretical summary for future research in the area of tiny resistors.
