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 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 ± 1 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.
Calibration
The meter needs to be calibrated and tested on a regular basis to ensure
it produces accurate measurement results. We recommend carrying out
calibration once a year.
Information on maintenance and care
Clean all components with a damp cloth and do not use cleaning agents,
scouring agents and solvents. Remove the battery(ies) before storing for
longer periods. Store the device in a clean and dry place.
