To Check The Accuracy Of Cross Line Laser - ADA INSTRUMENTS 3D LINER 2V Operating Manual

3D LINER
TO CHECK THE ACCURACY OF LINE LASER LEVEL
Set up the instrument between two walls, the distance is 5 m.Turn on the 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 spesifications), there is no need in calibration.
Example: when you check the accuracy of 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 Line Laser isn't corresponding with claimed accuracy, contact the authorized service center.
