A diagnostic device for determining an out-of-roundness on wheels of rail vehicles within a specified measuring section, comprising a plurality of force sensors, which are designed to determine forces acting on them and are connected to an evaluating device, wherein the evaluating device is provided for determining the out-of-roundness by integrating a force signal F, which is forwarded by the force sensors over time in order to determine an impulse. A method is also provided for determining an out-of-roundness on wheels of rail vehicles within a specified measurement section, wherein the force signals of at least one force sensor are fed to an evaluating device, the evaluating device detects an impulse, and the evaluating device integrates a force signal over a defined time interval and thereafter uses said force signal to output a result.
