Direct the laser against the close wall A and allow the meas-
uring tool to level in. Mark the centre of the point where the
laser lines cross each other at wall A (point I).
Turn the measuring tool by 180°, allow it to level in and
mark the cross point of the laser lines on the opposite wall
B (point II).
Without turning the measuring tool, position it close to wall
B. Switch 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
results in the actual height deviation of the measuring tool
alongside the lateral axis.
On the measuring distance of 2x5m=10m, the maximum
allowable deviation is:
10mx±0.2mm/m=±2mm.
Thus, the difference d between points I and III must not ex-
ceed 2 mm (max.).
Checking the Levelling Accuracy of the Vertical Lines
For this check, a door opening is required with at least 2.5 m
of space (on a firm surface) to each side of the door.
Position the measuring tool on a firm, level surface (not on
a tripod) 2.5 m away from the door opening. Switch on the
measuring tool to operation with automatic levelling. Se-
lect an operating mode in which a vertical laser plane is
generated in front of the measuring tool.
Mark the centre of the vertical laser line at the floor of the
door opening (point I), at a distance of 5 m beyond the
other side of the door opening (point II) and at the upper
edge of the door opening (point III).
Rotate the measuring tool by 180° and position it on the
other side of the door opening directly behind point II. Al-
low the measuring tool to level in and align the vertical laser
