Optional: Working with the laser receiver
Use an laser receiver (optional) to carry out levelling at great distances or
when the laser lines are no longer visible.
To work with a laser receiver, switch the line laser into hand receiver mode
with the hand receiver mode button (10). The bubble level flashes green.
The laser lines will now pulsate with high frequency, making the laser lines
darker. The laser receiver can detect these pulsating laser lines.
!
Follow the operating instructions of the corresponding laser receiver.
Checking the vertical line:
Position the device about 5 m from a wall. Fix a plumb bob with a line of 2.5 m
length on the wall, making sure that the bob can swing freely. Switch on the
device and align the vertical laser to the plumb line. The precision is within the
specified tolerance if the deviation between the laser line and the plumb line is
not greater than ± 1.5 mm.
Checking the horizontal line:
Position the device about 5 m from a wall and
switch on the cross laser. Mark point B on the
wall. Turn the laser cross approx. 2.5 m to the
right and mark point C. Check whether the
horizontal line from point C is level with point B to within ± 2 mm. Repeat the
process by turning the laser to the left.
!
Regularly check the adjustment before use, after transport and after
extended periods of storage.
