1.8 Rotating Method of AP-L1A
1.8.1 Rotating of AP-L1A 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.
1.8.2 Using Software Key to Rotate AP-L1A
The instrument can be rotated in the directions of +90,-90,180 by operating soft keys. This
function can be used to level the instrument very accuracy with plate level after power ON.

 During auto rotating by soft keys, other operation keys or function keys do not function. Press
any keys except power key to stop rotation in progress.
 During auto rotating the instrument, don't disturb it by touching the instrument. Such action
may cause trouble or harm to the instrument or operator.
 AP-L1A is able to rotate automatically to a required horizontal angle or vertical angle set. Refer
to Chapter 4.4 "Rotating automatically to a required Horizontal and Vertical angle".
