Measuring Functions

Note: The specified levelling accuracy applies for the alignment of the laser beam with
reference to the spirit levels 3 and 4.
Positioning the Measuring Tool (see figure B)
For precise alignment with the spirit levels, the position of the measuring tool is im-
portant.
The listed levelling accuracy is only achieved when the measuring tool is properly
positioned:
– For horizontal alignment with spirit level 4, the laser outlet opening for line opera-
tion 5 must be horizontal and the aluminium supporting surface 2 of the measuring
tool must face downward.
– For vertical alignment with spirit level 3, the laser outlet opening for line operation
5 must face upward and the aluminium supporting surface 2 of the measuring tool
must face sideward.
Alignment with Laser Line (Line Operation)
Fasten the measuring tool to wall holder 13 (see "Fastening/Aligning with the Wall
Holder", page 20), place it against a wall via the three supporting points 6 or fasten it
to an other magnetic surface with the magnets 8.
Horizontal Alignment (see figures C–D): The laser outlet opening for line operation
5 must be horizontal and the aluminium supporting surface 2 of the measuring tool
must face downward. Horizontally align the measuring tool with spirit level 4. As an
example, you can align picture frames or shelves alongside the horizontal laser line.
Note: Horizontal alignment with the laser line is only possible on the surface, against
which the measuring tool was placed. Even when the measuring tool was aligned with
the spirit level, the laser line on a transverse wall does not necessarily run horizontal,
and is thus not suitable for levelling.
Vertical Alignment (see figure D): The laser outlet opening for line operation 5 must
face upward and the aluminium supporting surface 2 of the measuring tool must face
sideward. Vertically align the measuring tool with spirit level 3. As an example, you
can align top and base cabinets alongside the vertical laser line.
Alignment off of Reference Points (see figure E): Turn the measuring tool to any re-
quired angle in order to align the laser line alongside your reference points. As an ex-
ample, this can be used to hang picture frames parallel to stairs or to the incline of a
roof.
Projecting/Checking Heights via Laser Point (Point Operation) (see figure F)
Place the measuring tool on the wall holder and horizontally align it (see "Fasten-
ing/Aligning with the Wall Holder", page 20).
