Abstract

In the design of high-precision resistance calibrator, using the fitting algorithm to fit the resistance control curve is an important method of error compensation. The interpolation method and the approximation method are commonly used in the fitting algorithm. However, there exist overmuch test points and noise problems in the high accuracy resistance calibrator, which leads to the problem of low accuracy of interpolation and approximation. In order to realize accurately fitting, a fitting algorithm based on least squares approximation was used to fit the curve. The results show that the proposed algorithm can be applied to the error correction of the resistance calibrator, which greatly improves its accuracy.
