The LAX-200 crossed line laser is designed for use on construction sites and was
perfectly adjusted when it left our factory. As with any precision instrument,
however, its calibration must be regularly checked. The unit should be checked
before starting any new tasks, particularly when the unit has been exposed to
strong vibrations. After an impact, the unit should be checked throughout its
whole self-levelling range.
Checking the calibration
You must create a reference to perform this test.
Fasten a plumbline near to the wall.
The laser unit should now be set up in front of this reference mark
(distance Y) and the vertical laser line compared with it.
The discrepancy between the centre of the laser line and the reference mark
should be no greater than 1 mm over a length of 2 m.
