If points A2 and A3 are more than 0.4 mm / m apart on either
the X, Y or Z axis, the device is in need of adjustment. Contact

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.
Place the device on a surface that is as level as possible. Switch the device on.
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 and Z axis, repeat steps 3 and 4.
