on the wall.
3. Adjust the instrument, make the vertical laser line V2
covered with the line and pass through the marked point B
after auto-leveling finished.
4. Mark a point on the vertical laser line V1 on the wall as C
in the same height position with the marked point.
5. Measure the height difference as H between two marked
points A and C.
6. Hmax= Distance between the straight line and wall (m) ×
tan(vertical orthogonal accuracy) × 2
7. If H
≤
Hmax, the vertical orthogonal accuracy is correct.
