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.

Prism P

Prism height

Instrument height

When measuring coordinates of ground point A1 :Set the instrument height/prism height.

When measuring coordinates of point A0 : Set the instrument height only. (Set the prism height to 0 ).

When sighting to A0, 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.
