Preparing the calibration check:
It is possible for you to check the calibration of the laser. To do this, position the device midway between 2 walls,
which must be at least 5 m apart. Switch the device on (Laser cross ON). The best calibration results are achieved if
the device is mounted on a tripod.

If points A2 and A3 are more than 0.5 mm / m, the device is in need of calibration. Contact your authorised
dealer or else the UMAREX-Laserliner Service Department.
Checking the vertical line:
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 ± 2.5 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 ± 2.5 mm. Repeat the process by turning the laser to the left.
!
Regularly check the calibration before use, after transport and after extended periods of storage.

1. Mark point A1 on the wall.
2. Turn the device through 180° and mark
point A2. You now have a horizontal
reference between points A1 and A2.
3. Position the device as near as possible to
the wall at the height of point A1.
4. Turn the device through 180° and mark
point A3. The difference between points
A2 and A3 is the tolerance.
