As you rack the fine adjustment up, the air bubble will appear to move in the opposite direction. Similarly, as you rack the fine adjustment down, the air bubble will appear to move in the same direction. This movement is due to the changes in the position of the objective lens that affects the focus and the path of the light passing through the microscope.
