Laserliner AutoCross-Laser 3C Plus 031.213A [10/24] Autocross laser acl 3 p

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 ON). The best calibration results are achie-

ved if the device is mounted on 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.

180°



Note: If points A2 and A3 are more than 3 mm / 10 m, the device is in

need of calibration. Contact your authorised dealer or else the UMAREX-

LASERLINER Service Department.

2,5 m

< 2 mm = OK

180°

3 mm / 10 m = OK
