FIELD: measurement equipment.
SUBSTANCE: in calibration device with at least one sensor and with at least one exciting source, a control device to control the measurement system, a calibration medium and a drive that is intended to move the calibration medium under control of the control device in measurement system calibration mode to the position, in which the calibration medium is on the trajectory of beams in the measurement system, and when being changed over to the operating mode to check the analysed objects, and mainly bank-notes, to the position out of the trajectory of beams in the measurement system, calibration medium has more than one reference, and drive has the possibility of moving the calibration medium under control of the control device to the position, in which the calibration medium is on the trajectory of beams in the measurement system and one of the references of the calibration medium covers the active zone of the measurement system and in which the measurement system measures properties of that reference located in its active zone, as well as the possibility of at least single movement of calibration medium under control of the control device to the specified distance or to the distance that is divisible by that specified distance, to the position in which the active zone of the measurement system covers the other reference and in which the measurement system measures the properties of that reference located in its active zone; at that, the above specified distance corresponds to length of individual references of calibration medium in the direction, in which the drive moves the calibration medium.
EFFECT: invention allows providing accurate calibration at lower costs.
