– Aim the laser at the closer wall A and al-
low the measuring tool to level in. Mark
the middle of the point at which the laser
lines cross on the wall (pointI).

– Turn the measuring tool 180°, allow it to
level in and mark the point where the
laser lines cross on the opposite wall B
(pointⅡ).
– Position the measuring tool –without rotating it– close to wallB, switch it on and al-
low it to level in.

– Align the height of the measuring tool
(using the tripod or by placing objects
underneath as required) so that the
point where the laser lines cross exactly
hits the previously marked pointⅡ on
wallB.

– Turn the measuring tool 180° without
adjusting the height. Aim it at wallA
such that the vertical laser line runs
through the already marked pointⅠ. Al-
low the measuring tool to level in and
mark the point where the laser lines
cross on wallA (pointⅢ).
– The discrepancy d between the two marked pointsⅠ and Ⅲ on wallA reveals the ac-
tual height deviation of the measuring tool.
