Abstract: Disclosed is a method and a device for checking the quality of a crimping of a specified cable with a specified contact sleeve using a sensor system for measuring a force and a displacement of a device for the actuation and/or force application of a crimping unit and using an electronic analysis system. In the method a force/displacement curve is detected during the crimping process and is displayed on a screen, wherein the method has the following steps: a stored reference model is displayed on the screen together with the detected force/displacement curve, said reference model having a first and a second envelope curve which define a tolerance range;—comparing the force/displacement curve with the reference model, thereby ascertaining whether the force/displacement curve lies in the tolerance range; and—arriving at a conclusion regarding the quality of the crimping from the comparison.
