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