| Abstract: | For the practical purpose, presents a kind of fast mathematical model derived from principle of minimum zone to evaluate the linearity error. By means of a true line, the measured actual curve is divided into two areas. One of the areas is above the true line, and the other is below. So the optimum points which are in ac-cord with minimum condition can be obtained accurately. |
