Enter the reading values ​​of the measurement results point by point on the coordinate paper. As shown in Figure 12, first place the zero value point of the first trial number on the horizontal coordinate with the value of the first value, then determine the coordinate point of the second reading based on the previous coordinate point, and determine it by the value of the first reading, and then draw the coordinate points of the reading values ​​of each tooth sequence until the last tooth. Connect the coordinate points with a straight line, and finally connect the zero point of the first tooth and the coordinate point of the last tooth with a straight line. This straight line is the calculation of the accumulated error. The positive value is on the left side of the line and the negative value is on the right side of the line.
