TO CHECK THE ACCURACY OF LINE LASER
TO CHECK THE HORIZONTAL LASER LINE
Place the line laser on the tripod 10 m away from the wall so the horizontal
laser line will be directed to the wall. Switch on the power. The line laser
starts to self-level. Mark point A on the wall to show the contact of laser
beam with the wall. Turn the line laser by 90° and mark points В, С, D on the
wall. Measure distance “h” between the highest and lowest points (these are
A and D points in the picture). If “h”is ≤ 6 mm, the measurement accuracy
is good. If “h” exceeds 6 mm, apply service center. Repeat these actions to
check the horizontal laser line. Test results apply only to the tested beam.
TO CHECK PLUMB
Choose a wall and set laser 5m away from the wall. Hang a plumb with the
cord about 2,5 m long on the wall. Switch ON the line laser and direct the
vertical line to the plumb with the cord. The accuracy of the line is within
acceptable limits if the deviation of the vertical line (up or down) does not
exceed half the value of the “accuracy” characteristic (+/-3mm per 10m). If
the accuracy of the line laser does not correspond to the declared one, it is
