Preparing the calibration check
It is possible for you to check the calibration of the laser. To do this, position the device
midway between 2 walls, which must be at least 5 metres apart. Switch the unit on and
use the SensoLite to define the marking points. For optimum results, please use a tripod.
1.
Mark point
A1
on the wall. (Use spot mode.)
2.
Turn the device through 180° and mark point
A2
. You now have a horizontal
reference between points
A1
and
A2
.
Performing the calibration check
3.
Position the device as near as possible to the wall at the height of point
A1
.
Now adjust the device in the X axis.
Mark either levelling screw A or B as a reference screw. Align the unit only
with the other levelling screws.
!
4.
Turn the device through 180° and mark point
A3
. The difference between points
A2
and
A3
is the tolerance for the X axis.
5.
To check the Y axis, repeat steps 3 and 4.
