To check the accuracy of line laser level

To check the accuracy of line laser level (slope of plane)

Place laser level on the tripod 5m away from the wall so the horizontal laser line will be directed to the wall.
Switch on the power. The instrument starts to self-level. Mark point A on the wall to show the contact of laser beam
with the wall. Turn the instrument 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.
