By using a tripod or a wall bracket, if necessary, align the height
of the measuring tool in such a way that the cross point of the
laser lines is projected against the previously marked point
the wall B. Without changing the height, rotate the measuring
tool by 180', direct the laser beam against the wall A so that
the vertical laser line runs through the already marked point I,
Allow the measuring tool to level in and mark with

2x5m = 10m, the maximum allowed deviation is: (± 0.2 mm / m
= 0,2mmx10m = ± 2 mm). The difference between the marked
