Measuring Functions
Note: The specified levelling accuracy applies for the
alignment of the laser beam with reference to the spirit
levels 6 and 7.
Positioning the Measuring Tool (see figure B)
For precise alignment with the spirit levels, the posi-
tion of the measuring tool is important.
The specified levelling accuracy is only achieved when
the measuring tool is correctly positioned:
– For horizontal alignment with the spirit level 7, the
aluminium supporting surface 8 of the measuring
tool must face downward.
– For vertical alignment with the spirit level 6, the exit
opening for the laser beam 9 must face upward.
Aligning with the Laser Line
Horizontal Alignment (see figures C–D): Position the
measuring tool with the three supporting points 12
against the wall or with help of the magnets 14, fasten
it to the wall holder 1 or to another magnetic surface.
The aluminium supporting surface 8 of the measuring
tool must face downward. Align the measuring tool
horizontally with help of the spirit level 7. Picture
frames or tiles, as an example, can be aligned along-
side the horizontal laser line.
