Performing the calibration check
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.

4.
If points A2 and A3 are more than 0.15 mm / m, the device is in
!
need of calibration. Contact your authorised dealer or else the
UMAREX-LASERLINER Service Department.
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 ± 0.75 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 ± 0.75 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.
