SETTING UP THE ANGULAR PRISM
Before the centering process can start the laser beam has to be leveled. The
easiest way to achieve this is to use the tape measure to set the distance
between the laser beam and the floor equally on two locations; the first
location close to the T220, the second location close to the Angular Prism.
Position the tripod with the Angular Prism over the reference line at the roll
you want to measure. Roughly adjust the Angular Prism horizontally and
vertically , by raising/lowering the tripod and using the Slide Table, so that
the laser beam hits the center of the Angular Prism. The deflected beam
should run along the roll to be measured at a distance from the roll between
50 – 200 mm (2” – 7,5”). The tripod should rest stable on the floor and the
tripod platform be roughly leveled.
