Do not direct the laser beam at persons or animals and do not stare into the laser
u
beam yourself (even from a distance).
When switching on the measuring tool for the first time, you will be prompted to set your
preferred language for the display text.

The measured values and device settings in the memory are retained when you switch off
the measuring tool.

Measuring process

When switching on for the first time, the measuring tool will be in the length measure-
ment function. When switching on every subsequent time, the measuring tool will be in
the measuring function that was last used. For a different measuring function, press the
(2) [Func] button. Use the (6) [+] button or the (3) [–] button to select the required
measuring function (see "Measuring Functions", page 44). Activate the measuring func-
tion with the (2) [Func] button or with the measuring button (5) [ ].
There are three settings available for the reference level for measurement (see "Selecting
the reference level (see figure B)", page 43).
Apply the measuring tool to the point at which you want to start the measurement (e.g.
wall).
Note: If the measuring tool has been switched on using the on/off/back button (8) [ ],
briefly press the measuring button (5) [ ] to switch the laser on.
To initiate the measurement, briefly press the measuring button (5) [ ]. The laser beam
will then switch off. For a further measurement, repeat this process.
Do not direct the laser beam at persons or animals and do not stare into the laser
u
beam yourself (even from a distance).
Note: The measured value typically appears within half a second, and no later than ap-
proximately four seconds. The duration of the measurement depends on the distance,
the lighting conditions and the reflective properties of the target surface. Upon comple-
tion of the measurement, the laser beam will automatically switch off.
Selecting the reference level (see figure B)
You can choose between three different reference levels for the measurement:
– The rear edge of the measuring tool (e.g. when placing against walls)
– The front edge of the measuring tool (e.g. when measuring from a table edge)
– The centre of the thread (14) (e.g. for tripod measurements)
To select the reference level, press the (7) [ ] button. Then select the "Reference level"
setting with the measuring button (5) [ ] or the (2) [Func] button. Then use the (6) [+]
