That is to say, the bases of the five rings and the three rings of the health pot are different. So it can't be changed. Three rings, the first two rings are significant figures, and the third ring is the ratio; In the case of four rings, the first and second rings respectively represent the resistance of two significant figures; The third ring represents the magnification; The fourth ring represents an error. In the case of five rings, the first, second and third rings respectively represent the resistance of three significant figures; The fourth ring represents the magnification; The fifth ring stands for error.
