Measuring functions
Note: The specified levelling accuracy applies for the align-
ment of the laser beam with reference to the spirit levels
for vertical alignment (3) and for horizontal alignment (4).
Positioning the Measuring Tool (see figure B)
For precise alignment with the spirit levels, the position of
the measuring tool is important.
The listed levelling accuracy is only achieved when the
measuring tool is properly positioned:
– For horizontal alignment using the spirit level for hori-
zontal alignment (4), the aluminium supporting
surface (2) of the measuring tool must face downward.
– For vertical alignment using the spirit level for vertical
alignment (3), the laser outlet aperture for line
operation (5) must face upward and the aluminium sup-
porting surface (2) of the measuring tool must face to
the side.
Alignment with Laser Line (Line Operation)
Position the measuring tool with the three supporting
points (6) against the wall or with help of the magnets (9),
fasten it to the holder (14) or to another magnetic surface.
Horizontal alignment (see figures C–D): The aluminium
supporting surface (2) of the measuring tool must face
downward. Horizontally align the measuring tool using the
spirit level (4). As an example, you can align picture
frames or shelves alongside the horizontal laser line.
Note: Horizontal alignment using the laser line is only pos-
sible on the surface against which the measuring tool was
placed. Even if the measuring tool has been aligned using
the spirit level, the laser line on a transverse wall does
