5. Check the vertical laser line accuracy
5.1 Find a 3m wall and place the laser 3 m away from the wall.
5.2 Turn on the laser lines and mark point A on the wall.
Please note the distance from point A to ground should be 3 m.
5.3 Hang a plumb line from A point to ground and mark the plumb point B on
ground.
5.4 Turn on the laser to make the vertical laser line to meet point B on the
ground.
5.5 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.
