    Set-ups 1 to 3 show typical set-up using the fittings supplied with the standard XR20 kit . Always ensure the mounting surface of the table under test and the XR20 facing ring are clean and free of swarf, debris and burrs . Mounting set-up 1 (default configuration) In most applications, the facing ring of the XR20 can be mounted directly to the surface of the axis under test (as shown) using the mounting ring .
