WebStraightness measurements with the Arc Angle method are made by setting the laser beam roughly parallel to a centerline. Two points are used as references. The sensor is placed in three to nine positions at each measurement point to find the center of the measurement object. For the Arc Angle measurements, the detector is in a single-axes … WebThe basic principle of straightness measurement is that all measurement values will show the position of the detector unit relative to the laser beam. The laser beam can be envisioned as a very, very long, absolutely straight and weightless ruler. First, the beam is roughly aligned along the measurement object.
