Working with Automatic Levelling
Position the measuring tool on a level and firm support or mount it to the tripod
11
.
Select one of the operating modes with automatic levelling.
After switching on, the levelling function automatically compensates irregularities
within the self-levelling range of ±4°. The levelling is finished as soon as the laser
beams do not move any more.
If automatic levelling is not possible, e.g. because the surface on which the measuring
tool stands deviates by more than 4° from the horizontal plane, the laser switches off.
If this is the case, set up the measuring tool in a level position and wait for the self-lev-
elling to take place.
In case of ground vibrations or position changes during operation, the measuring tool
is automatically levelled in again. To avoid errors, check the position of the horizontal
and vertical laser line with regard to the reference points upon re-levelling.
Operating Mode
Cross-line operation (with automatic levelling): Generates a horizontal
and a vertical laser line.
Cross-line and plumb point operation (with automatic levelling):
Generates a horizontal and a vertical laser line and two plumb points.
Cross-line operation (without automatic levelling): Generates a horizontal
and a vertical laser line.
