Abstract
A method for calibrating a coin checking device includes inserting a calibrating module into a coin passage. The coin passage contains at least one coin sensor for determining a coin's physical features. The calibrating module generates measuring signals which simulate an acceptable coin's presence. The measuring signals are received by the at least one coin sensor which in turn outputs sensor signals. The measuring signals and the sensor signals are used to calculate a calibration factor for the coin checking device.
