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.
Always perform a thorough and complete calibration to avoid incorrect measuring res-
ults.
– Attach the measuring tool to a vertical surface.
– While the measuring tool is either switched on or off, press and hold the on/off but-
ton (2) until the laser beam starts flashing and the light-up ring (3) is no longer lit.
– Slowly and evenly rotate the housing of the measuring tool once by more than 360°
(either clockwise or anticlockwise). The rotation should take at least 15 s.
– The calibration process is completed successfully once the light-up ring (3) lights up
green.
– If the light-up ring (3) lights up red after calibration, the calibration has failed. Restart
the calibration.
