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 device on. The best calibration
results are achieved if the device is mounted on a tripod. IMPORTANT: The automatic sensor must
be active.
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.
