Indication Description
The measuring tool starts.
When no button on the measuring tool is pressed for approx. 30 minutes,
the measuring tool automatically switches off to save the batteries.
Automatic Levelling (see figures E – F)
Position the measuring tool on a level and firm support or mount it to the
tripod 12.
Select one of the operating modes with automatic levelling.
After switching on, the automatic levelling function automatically com-
pensates irregularities within the self-levelling range of ±4 °. The levelling
is finished as soon as the laser lines do not move anymore. The operating
mode appears in the display.
If the automatic levelling function is not possible, e. g. because the sur-
face on which the measuring tool stands deviates by more than 4 ° from
the horizontal plane, the display 4 flashes and the laser is switched off au-
tomatically (see figure F). If this is the case, set up the measuring tool in a
level position and wait for the self-levelling to take place. As soon as the
measuring tool is once again within the self-levelling range of ±4 °, the op-
erating mode appears in the display 4 and the laser is switched on.
When not within the self-levelling range of ±4°, working with automatic
levelling is not possible, because it cannot be assured that the laser lines
run at a right angle to each other.
In case of ground vibrations or position changes during operation, the
measuring tool is automatically levelled again. Upon re-levelling, check
the position of the laser lines with regard to the reference points to avoid
errors.
Tilt function with angle indicator
In this operation mode, the measuring tool generates a horizontal or two
crossed laser lines, which can be freely aligned. The tilt angle is shown in
the display.
