Checking the laser level
You should regularly check the following parameters of the laser level
- setting a horizontal plane
- cone error
- setting a vertical plane
Checking and calibration of the horizontal and vertical planes is simple and in most cases can
be done by the user. Checking the cone error can be also done by the user, but this error can
be only removed by an authorized service center.
Checking the horizontal plane
(1) Checking
Set the instrument about 30m from the wall so that the X-axis is perpendicular to the wall and X
direction a pointed to a wall.
Turn on the instrument and wait until it level automatically.
Place a sheet of paper on the wall. Mark the position of the laser beam (Ma) on the sheet. Turn
off the instrument.
Loosen the tripod fixing screw and rotate the instrument 180 °.
WARNING!
Be careful not to move the instrument while the head is spinning.
Turn on the instrument once again and wait until it level automatically.
Once again mark the position of the laser beam on the sheet (Mb).
Measure the distance between the marks Ma and Mb, if the distance is less than 6 mm
calibration is not necesary, in other case please contact service center
Perform similar operations for the Y axis .
