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.
Claims15
A method for calibrating a coin checking device including at least one sensor, the method including the steps of inserting a calibrating module in a coin passing section accommodating all of said at least one sensor, generating sensor signals representing a physical feature of an acceptable coin by generating at least one measuring signal with the calibrating module, calculating a calibrating factor from the measuring signal determining at least one reference value from the sensor signals generated in the sensor, and storing said each reference value in a RAM memory of the coin checking device.
A calibrating device for calibrating a coin checking device accepting at least a coin, said coin checking device comprising at least one sensor and a coin passage section, wherein each sensor is associated with the coin passage section and generates a sensor signal representing a physical feature of a coin running in said passage section, the coin checking device further comprising a RAM memory in which at least a reference value is loaded which corresponds to said sensor signal, the calibrating device comprising a calibrating module which is inserted in said passage section in a predetermined position, wherein the calibrating module includes at least a simulation means which simulates said physical feature and interacts with the sensor, and the calibrating device further comprises a simulation generator, wherein the simulation generator is connected to the simulating means, delivering a control signal to the simulation means.
