8.3 Angle check
Checking the 90° angle
1. Mark point A on the floor at a distance of
10 m (32'10") in a sufficiently large corner
of the room.
2. Align the LAX 600/LAX 600G with point A
using the plumb-line dot.
3. Align the LAX 600 / LAX 600G with the one
wall using a laser line.
4. Precisely mark point B on the floor at the
halfway point.
5. Precisely mark point C on the wall or floor.
6. Shift the LAX 600 / LAX 600G and align with
point B using the plumb-line dot.
7. Align the LAX 600 / LAX 600G with point C
again using the laser line.
8. Precisely mark point D on the other wall or
on the floor using the 90° laser line.
Note:
The distance from A to B, B to C and B to D
should be the same to guarantee accuracy.
9. Turn the LAX 600 / LAX 600 G through 90°
and align the first laser line with point D.
10. Mark position E on the perpendicular second
laser line as close as possible to point A.
11. Measure the distance between points A to E.
