5 PROGRAM MODES
5.6.1 Angle Offset
This mode is useful when it is difficult to set up the prism directly, for example at the center of a tree.
Place the prism at the same horizontal distance from the instrument as that of point A0 to measure.
To measure the coordinates of the center position, operate the offset measurement after setting the
instrument height/prism height.

, you can select one of two
ways. [HOLD] is to fix vertical angle to the prism
position even updown the telescope position, and
[FREE] is to gear vertical angle to the updown of
telescope movement. In case following the
vertical angle to the movement of telescope,
SD(Slope Distance) and VD(Vertical Distance)
will be changed according to the movement of
telescope.
