An apparatus for angle measurement that includes a graduation carrier with a code track disposed concentrically to a center point of the graduation carrier. The apparatus includes a first scanning unit having a first interface and a second scanning unit having a second interface, wherein the first and second scanning units ascertain angle values of the graduation carrier by scanning the code track. The apparatus further includes a control unit having: 1) a device interface that is in communication with a follower electronics unit, 2) a control unit interface that is in communication with the first and second interfaces and 3) a processing unit. By which the processing unit, angle values of the first and second scanning units can be requested and processed into a corrected angle value, and the corrected angle value can be transmitted to the follower electronics unit via the device interface.
