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
