Checking the wobble angle
After the calibrated control device has been installed with the correct
interchangeable disc on a roller, the laser arm is rotated.
In doing so, the laser beam draws a circular track on the inter-
changeable disc. If this circular track remains within the interchange-
able disc, the wobble angle is within the tolerance range of ±0.2°.

Determining the wobble angle from the other side
Install the laser arm and the target disc respectively on the bearing
pins on the other side of the roller and repeat the measurement from
the other side.
