Abstract
A method for the compensation of disturbances upon magnetic measurements on value documents, in which a sensor having several measuring tracks for generating measurement signals is employed, in which for each value document a specified number of data records is generated, the value document not being captured by at least one of the measuring tracks during the measurement, wherein from the measurement signal of the at least one measuring track there is ascertained a value for the quantity of a disturbance present in the region of the sensor during the measurement on the value document, and a compensation of the deviations of the measurement signals of the measuring tracks capturing the value document, which deviations are caused by the disturbance present during the measurement, is carried out by means of said ascertained value for the quantity of the disturbance.
