Mark the position of the visible laser line cross on the wall B (point 2).
Mark the position of the visible laser line cross on the wall A (point 1).
Switch the unit on.
Set the LAX-50 on a smooth level surface or on the tripod with the front
facing the wall.
Turn the complete unit 180° without altering the height of the laser.
Two parallel wall surfaces at least 5 m apart are required for the
horizontal check.
Without changing the height of the laser, rotate it 180° to place the beam
near the mark on the first wall (step 3 / point 1 ).
Measure the vertical distance between point 1 and
point 3. The difference must not be greater than
5 m
10 m
15 m
5,0 mm
10,0 mm
15,0 mm

Now move the unit directly in front of wall B.
Set the unit's height so that the laser dot's height matches that of
point 2.

1. Horizontal checking - Line level
2. Horizontal checking - inclination of the laser line
Check the laser line for inclination and perfectly straight
projection.

Place the instrument in front of wall A - distance X = 5 m.
Rotate the instrument through 45°.
The distance of the laser line (= point 4) from point M must not exceed 1,5 mm.

Calculate the centre line between point 1 and
point 3 and mark it (point M).
Rotate the instrument through 90°.
The distance of the laser line (= point 5) from point M must not exceed 1,5 mm.
