Offset Measurement; Angle Offset - Horizon Fitness HTS-580 Series Operation Manual

5.6 Offset Measurement

There are four offset measurement modes:

1. Angle offset

2. Distance offset
3. Plane offset
4. Column offset
5.6.1 Angle Offset
This mode is useful when it is difficult to set up the prism directly on target; 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 use the offset measurement after setting the instrument height/prism
height.
When measuring coordinates of ground point AI: Set the instrument
height/Prism height
When measuring coordinates of point A0: Set the instrument height only (Set
the prism height to 0)
