To check the accuracy of line laser level
To check the accuracy of line laser level (slope of plane)
Set up the instrument between two walls, the distance is 5 m.
Turn on the Cross Line Laser and mark the point of cross
laser line on the wall.
Set up the instrument 0,5-0,7m away from the wall and make,
as described above, the same masrks. If the difference {a1-
b2} and {b1-b2} is less then the value of "accuracy" (see spe-
sifications), there is no need in calibration.
Example: when you check the accuracy of Cross Line Laser
the difference is {a1-a2}=5 mm and {b1-b2}=7 mm.
The instrument's error: {b1-b2}-{a1-a2}=7-5=2 mm. Now you
can compare this error with standard error.
If the accuracy of Cross Line Laser isn't corresponding with
claimed accuracy, contact the authorized service center.

To check level
Choose a wall and set laser 5M away from the wall. Turn on
the laser and cross laser line is marked A on the wall. Find
another point M on the horizontal line, the distance is around
2.5m. Swivel the laser, and another cross point of cross laser
4
line is marked B.
Please note the distance of B to A should be 5m.
Measure the distance between M to cross laser lune, if the
difference is over 3mm, the laser is out of calibration, please
contact with seller to calibrate the laser.
To check plumb
Choose a wall and set laser 5m away from the wall. Mark
point A on the wall, please note the distance from point A
to ground should be 3m. Hang a plumb line from A point to
ground and find a plumb point B on ground. turn on the laser
and make the vertical laser line meet the point B, along the
vertical laser line on the wall and measure the distance 3m
from point B to another point C. Point C must be on the verti-
cal laser line, it means the height of C point is 3m.
Measure the distance from point A to point C, if the distance
is over 2 mm, please, contact with seller to calibrate the laser.
