Light-up ring
Levelling
Red
The laser line is neither horizontal nor vertical. Turn the housing of
the measuring tool so that it is horizontal or vertical as required.
Yellow
(only one corres-
ponding half of the
light-up ring is dis-
played)
The laser line is close to being completely horizontal or vertical. To
precisely adjust the laser line, turn the housing in the direction of
the lit half of the light-up ring.
Green
The laser line has been successfully levelled in either horizontally or
vertically.
After successfully levelling in the laser line, make sure to let go of the housing carefully
without rotating it again.
Working Advice
Working with the tape measure (see figure D)
The zero point of the tape measure
(12)
is situated in the centre of the marking aid
(1)
and can be marked directly on the substrate.
Note:
The zero point marking can be offset by up to ±1 mm compared to the laser line.
Pull the tape measure housing
(11)
away from the measuring tool and mark additional
points at the required distances at the height of the laser line. When marking, ensure that
the light-up ring
(3)
continues to be illuminated green and that the measuring tool is con-
sequently levelled in.
Do not pull the tape measure
(12)
out any further than up to the end of the imprinted
scale.
The tape measure will roll itself up again automatically. Hold the tape measure hous-
ing
(11)
with a relaxed grip and allow the tape measure to slowly retract itself. Make sure
that the tape measure housing engages in the recess on the measuring tool.
Note:
Do not let go of the tape measure while it is unrolled. Uncontrolled retraction may
damage the tape measure.
Calibrating the Laser Line
Calibration should be carried out in the following cases:
– After the tool has been dropped or subjected to heavy impact
– Every 6 months
If necessary, check the levelling of the laser line on a known horizontal or vertical refer-
ence line.
