If points A2 and A3 are more than 1 mm / 10 m (DuraMax) / 0,5 mm / 10 m (DuraMax XPro)
apart on either the X or Y axis, the device is in need of adjustment. Contact your authorised
dealer or else the UMAREX-LASERLINER Service Department.

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 for the X axis.
5.
To check the Y axis, repeat steps 3 and 4.
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 metres apart. The best calibration results are achieved
if the device is mounted on a tripod. Switch on the device and determine the marking points using
the laser receiver. When doing this, set the laser receiver to the maximum precision level.
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.
