 Horizontal Rotation Cone Error
Perform the following check after completing “Horizontal Rotation Grade Error” on the previous
page.
1 Set up the laser centered between two walls approximately 50 m (164 ft) apart. Orient the
instrument so one axis, either X or Y, is facing the walls. Grade should be set to 0% in both
axes.
2 Locate and mark the position of the RL-SV2S beam on both walls using the LS-80L.
3 Turn off the RL-SV2S and move the RL-SV2S closer to wall A (1 m to 2 m /3 ft to 6 ft).
Do not change the axis orientation of the RL-SV2S. Turn the RL-SV2S on.
4 Again locate and mark the position of the RL-SV2S beam on both walls using the LS-80L.
5 Measure the distance between the first and second marks on each wall.
