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. Switch the unit on and
use the SensoLite to define the marking points. For optimum results, please use a tripod.
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.

Performing the calibration check
3. Position the device as near as possible to the wall at the height of point A1. Now
adjust the device in the X axis.
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.

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