Rotating Method
1.8.1 Rotating by H/V Shuttle and H/V Jog
H/V shuttle or H/V jog can be used to rotate the instrument manually. The shuttle movement or
displacement is proportional in speed and size of angle desired. A small, slow turn of the shuttle will
result in a slow small angle displaced. Likewise, a larger abrupt turn of the shuttle will result in a coarse
angle displacement. H/V jog can be used for accurate collimating of the target much like a standard
tangent screw.
