Set up the instrument 0,5-0,7m away from the wall and make, as described
above, the same marks. If the difference {a1-b2} and {b1-b2} is less than the
value of “accuracy” (see spesifications), 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 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 cal-
ibrate the laser.
