ACCURACY CHECK
The user is expected to carry out periodic checks of the product's accuracy and general performance.
1. Mount the instrument onto a tripod and set it up 20 m apart from a wall - the X axis showing to the
wall.
2. Switch on the instrument and let the laser complete the self-levelling process.
3. Mark the laser beam on the wall with point „A" .
4. Turn the instrument in 90° steps and mark the points „B" , „C" and „D" accordingly.
5. Measure the distance „h" between the highest and lowest point from „A" , „B" , „C" and „D" .
6. If „h" < 2 mm, the accuracy is okay. If the difference is beyond please have the instrument adjusted.
