Balance check:
The pressure ball on the support, according to its swing situation, the position of the load body for appropriate adjustment, and then screw the load body tight, the pressure ball re put on the support, observe the swing situation, in order to determine the adjustment effect. Only when the pressure ball is balanced can it be placed smoothly; otherwise, the pressure ball will swing obviously. If it is detected by optical equipment, the accuracy of test results will be seriously affected.
