Cross lines Note) In case the cross lines are tilted, adjust them by turning the chart, which is screwed in the rear tube of the equipment.
�� Unlock the holder-moving lever, and move the holder down slowly by the lever. Caution: Move the holder down so that a load is not put on the lens body (especially the three rollers that support the 4th lens group). Also, adjust so that the cross lines remain unmoving, when the knobs of the micrometer (X and Y axes) are rotated and the holder is moved up and down.
