A large US manufacturer has an application where they need to align 2 painted metal surfaces to be parallel to one another very accurately and quickly. By using the AP820-240 model which has a laser line length of 120 mm the laser line is place across the 2 metal surfaces. The laser line with the use of the AcuityView software program can measure the angle of the 2 surfaces to one another. The tolerances of +/- 3 degrees was set in the software and a green button is shown when the 2 surfaces are in tolerance and the red button is seen when the surfaces are out of tolerance. The gap between the 2 surfaces can easily be seen and also measured if needed.
