There is an adjustment knob opposite the dial that moves the glass plate and its frame.

The knob rotates very smoothly and the max range of movement of the frame is about 3.5 mm. The dial indicator changes based upon the pressure applied by the frame on the glass plate.
The only markings on the case are" Kirem" and "Koinzidenz - MaBstab" and on the face of the dial indicator it reads "Carl Mahr esslingen aN" [sic].
