Operation
Start-Up
Never leave the measuring tool unattended when switched on, and ensure the
u
measuring tool is switched off after use. Others may be dazzled by the laser beam.
Protect the measuring tool from moisture and direct sunlight.
u
Do not expose the measuring tool to any extreme temperatures or variations in
u
temperature. For example, do not leave it in a car for extended periods of time. In
case of large variations in temperature, allow the measuring tool to adjust to the ambi-
ent temperature before putting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperatures or variations in temperat-
ure.
Avoid substantial knocks to the measuring tool and avoid dropping it. Always
u
carry out an accuracy check before continuing work if the measuring tool has been
subjected to severe external influences (see "Checking accuracy and calibrating the
inclination measurement (see figures E1–E2)", page 39).
Switching on/off
– To switch on the measuring tool and the laser, briefly press the measuring button (2)
[ ].
– To switch on the measuring tool without the laser, briefly press the on/off button (5)
[ ].
Do not direct the laser beam at persons or animals and do not stare into the laser
u
beam yourself (even from a distance).
To switch off the measuring tool, press and hold the on/off button (5) [ ].
The measured values and device settings in the memory are retained when you switch
the measuring tool off.
Measuring process
Once switched on, the measuring tool is in the length measurement function. For a differ-
ent measuring function, press the [Func] button (7). Use the [+] button (3) or the [–]
button (8) to select the required measuring function (see "Measuring functions",
page 33). Activate the measuring function with the [Func] button (7) or with the meas-
uring button (2) [ ].
Once the measuring tool has been switched on, the rear edge of the measuring tool is se-
lected as the reference level for measurement. To change the reference level (see "Se-
lecting the reference level (see figure A)", page 33).
