Automatic levelling
■
Place the appliance on a firm horizontal surface to work with auto-
matic levelling or fasten it onto a tripod via the 1/4" thread
■
After switching on, the automatic levelling system automatically
compensates for irregularities within the self-levelling range of
± 4°. Levelling is complete as soon as the laser lines no longer
move and the LED
■
If automatic levelling is not possible, e.g. because the underside
of the measuring tool is off the horizontal by more than 4° or be-
cause you are holding the appliance in your hand, then the LED
will light up red and the appliance will work without automatic
levelling. The laser lines will remain lit and flash, but the two
crossed lines will not necessarily run at right angles to each other.
NOTE
►
When you are working without automatic levelling, this is
always indicated by the red LED
►
After vibrations or position changes during operation, the
appliance will always automatically re-level itself. To avoid
errors, always check the position of the horizontal and/or
vertical laser line in relation to reference points after re-
levelling.
