3.Use A as a starting point and nail one end of a string with plumb bob (not included) on A. The length of the string should be 16 ft.
4.Mark M1 16 ft. from point A on the string.
5.Mark M2 8 ft. below the intersection of the beams on the vertical line.
6.Measure the distance between M1 and M2.
7.If the distance is less than or equal to
2 mm, the accuracy is within tolerance. Otherwise, take the instrument to a qualified technician for repair.
After Using Laser
