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.

Problem
Corrective measures
The light-up ring
(3)
flashes yellow 3 times
during operation, then the measuring tool
switches off.
Replace the battery.
The measuring tool is not within the operat-
ing temperature range specified in the
technical data and switches itself off.
Allow the measuring tool to reach the cor-
rect temperature and switch it back on
once it is back within the operating temper-
ature range.
The gel pad
(14)
does not affix properly.
– Check whether the substrate is suitable
for the gel pad.
– If the gel pad is dirty, it should be
cleaned.
– If the gel pad is damaged, it should be
replaced.
The laser line is not vertical or horizontal as
required after it has been levelled in.
Calibrate the laser line.
