Checking the cone error
Please do this procedure after calibration of horizontal plane.
Set the laser centered between the walls distanced from each other of 30 m. Set the instrument
in the X or Y direction.
Mark the position of the laser beam on both walls.
Turn off the instrument and move it near to the of one of the walls (1 to 2 meters). Do not
change the orientation of the axes. Turn on the instrument.
Again, mark the position of the laser beam on the walls
Measure the distance between the marks on the walls.
If the difference in distance is less than 3 mm, it can be assumed that this error does not occur.
Warning! If this error is more than 3m, you should contact the service center.
Checking the vertical plane
This procedure should be done after calibration of the horizontal plane.
Checking
Set the laser centered between the walls distanced from each other of 30 m
Turn on the laser level.
Place the paper sheets on the walls and mark the position of the laser beam.
Turn off the instrument. Set the instrument in vertical position near to one of the walls.
Turn on the instrument.
Mark the position of the laser beam on the paper sheet. Measure the distance between the
markers
Do not change the position of the laser and spin it 180°.
Mark the position of the laser beam on the paper sheet. Measure the distance between the
markers
If the distance between the markers is less than 3mm calibration is not necesery.
