12. Calibration Check

Set up the laser leveller as described in point 1. (but on an
extremely well aligned tripod) and align it along a traverse
length of approximately 30 metres – starting with the X axis,
for example – and switch it on.
At the end of the traverse length, make a mark at the level
of the laser beam. After this, rotate the laser unit by 180°
and make another mark. Then do the same for the Y axis. If
all the marks are on top of each other or are only slightly
apart (maximum of 2 mm), adjustment is OK. If the marks
are a long way apart, you must get a specialist firm to check
the equipment and recalibrate it.
