the measuring tool on and allow it to level in.

– Align the height of the measuring tool (using a tripod or by underlaying,
if required) in such a manner that the cross point of the laser lines is
projected against the previously marked point II on the wall B.

– Without changing the height, turn around the measuring tool by 180°.
Direct it against the wall A in such a manner that the vertical laser line
runs through the already marked point I. Allow the measuring tool to level
in and mark the cross point of the laser lines on the wall A (point III).
– The difference d of both marked points I and III on wall A indicates the
actual height deviation of the measuring tool.
On the measuring distance of 2 x 5 m = 10 m, the maximum allowable
deviation is:
10 m x ±0.5 mm/m = ±5 mm.
Thus, the difference d between points I and III must not exceed 5 mm
(max.).
