Offset&Height
The point is set out with a known perpendicular and vertical offset from the horizontal and
vertical alignments respectively.
If the Offset&Height method is used, the offsets of the point may be stored as coordinates in the fixpoint job. The Stake Offset may be stored as the X coordinate and the
Stake Height Difference may be stored as the Y coordinate.
To select a point stored in the fixpoint job, place the cursor on the Stake Pt ID and press
the ENTER key. For more information on working with points in the fixpoint job, refer to the
TPS1200 User manual.
