3 TO CHECK THE ACCURACY OF LINE LASER (SLOPE OF PLANE)
Set up the line laser between two walls, the distance is 5m.Turn on the
Line Laser and mark the point of cross laser line on the wall. Set up the
line laser 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 spesifications), there is no need in calibration. Example:
when you check the accuracy of Line Laser the difference 3 is {a1-a2}=5
mm and {b1-b2}=7 mm. The line laser's error: {b1-b2}-{a1-a2}=7-5=2 mm.
Now you can compare this error with standard error. If the accuracy of Line
Laser isn't corresponding with claimed accuracy, contact the authorized
service center.
TO CHECK THE ACCURACY OF HORIZONTAL BEAM
4
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 hori-
zontal line, the distance is around 2.5m. Swivel the laser, and another cross
point of cross laser 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 vertical 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.
