Abstract
The invention relates to a checking unit for checking a material web and to a calibrating method for the checking unit. The checking unit is equipped with drive means for transporting the calibration medium past the checking unit in order to detect a multiplicity of measurement values of the calibration medium. The drive means are arranged in the housing of the checking unit in order for the drive means to be protected from moisture or contaminants from the environment. To obtain a transporting of the calibration medium past the checking unit in spite of the arrangement of the drive means in the housing, drive means are employed that are configured for a contactless interaction with the calibration medium and can transport the calibration medium past the checking unit contactlessly. For this purpose there is preferably used a magnetic interaction between the drive means and the calibration medium.
