8.2 Horizontal check
Checking the horizontal laser line level
Please ensure that you adhere as closely as possible to
the orientation of the unit as shown.
1. Place the LAX 600 / LAX 600G on a horizontal surface
or on a tripod at distance S of at least 5 m (16’5”) in
front of a wall, with the operator panel facing towards
the wall.
2. Switch the laser unit on and wait until it has automati-
cally levelled itself.
3. Mark the centre of the visible laser line on the wall
– measurement 1 (point 1). A receiver can also be used.
4. Rotate the entire laser unit through 90° without altering
the height of the laser (i.e. do not change the tripod
height). Allow the unit to level itself again automatically.
5. Mark the centre of the laser lines on the wall (point 2).
6. Repeat steps 4 and 5 twice to obtain points 3 and 4.
7. If the differences between the four control points are
less than 6 mm / 1/4” for a distance of 10 m / 32’10” ,
the unit is within its permitted tolerance of ±0.1 mm/m
(± 18” over 100ft) .
In this case, points 1 and 3 correspond to the X-axis
and points 2 and 4 to the Y-axis of the unit.
