Do the same for b1 and b2 (b1-b2). If the difference between the two results (a1-a2) - (b1-b2) is over
2,4 mm the accuracy is out of standard and the unit needs to be calibrated.
Check the vertical laser line accuracy:
1. Find a 3m wall and place the laser 3 m away from the wall.
2. Turn on the vertical line and mark point A on the wall.
Please note the distance from point A to ground should be 3 m.
3. Hang a plumb line from A point to ground and mark the plumb point B on ground.
4. Turn on the laser to make the vertical laser line to meet point B on the ground.
5. Follow the laser line from the ground and mark point C on the wall.
Please note the distance from point C to ground should be 3 m.
Measure the distance from point A to point C to be called "e". If "e" is over 2 mm the accuracy is out of
standard and the unit needs to be calibrated.
