Abstract
A device for the contactless determination of an electrical potential of an object, has an electrode and a potential controller which is electrically connected to the electrode. The potential controller changes a reference potential applied to the electrode to a final value in such a way that an electric field between the object and the electrode disappears at the final value if the electrode is located at a distance from the object. The electrical potential is determined from the final value.
