Checking the vertical line:
Position the device about 5 m from a wall. Fix a
plumb bob with a line of 2.5 m length on the wall, making sure that the bob
can swing freely. Switch on the device and align the vertical laser to the plumb
line. The precision is within the specified tolerance if the deviation between the
laser line and the plumb line is not greater than ± 1.5 mm.
Checking the horizontal line:
Position the device about 5 m from a wall and
switch on the cross laser. Mark point B on the wall.
Turn the laser cross approx. 2.5 m to the right and
mark point C. Check whether the horizontal line
from point C is level with point B to within ± 2 mm.
Repeat the process by turning the laser to the left.

Performing the calibration check:
3.
Position the device as near as possible to the wall at the height of
point A1.
4.
Turn the device
through 180° and
mark point A3. The
difference between
points A2 and A3 is
the tolerance.
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 device on
(LASER CROSS AND TILT FUNCTION ON)
. Please use
a tripod.
1.
Mark point A1 on the wall.
2.
Turn the device
through 180° and
mark point A2.
You now have a
horizontal reference
between points A1
and A2.

Note:
If points A2 and A3 are more than 2 mm / 10 m, the device is in
need of calibration. Contact your authorised dealer or else the UMAREX-
