以当前板位的中心坐标设计值为基点，向左或者向右移动一个微小的距离，微小

Based on the design value of the center coordinate of the current plate position, move a small distance to the left or right, the length of the small distance is 0.1 mm, and the small distance of the movement is used as the position error calibration of the current plate position, and the maximum small movement is The cumulative movement range is ±5.0 mm, and the system automatically saves it according to the user's operation.

Based on the design value of the center coordinate of the current plate position, move a small distance to the left or right, the length of the small distance is 0.1 mm, and calibrate the small distance as the position error of the current plate position. The maximum cumulative moving range of the small movement is ± 5.0 mm, which is automatically saved by the system according to the user's operation.

Based on the design value of the center coordinate of the current board position, move a tiny distance to the left or right, the tiny distance length is 0.1 mm, and the tiny distance moved is calibrated as the position error of the current board position, and the maximum cumulative movement range of tiny movement is ±5.0 mm, which is automatically saved by the system according to the user's operation.
