摘要

The determining device includes a compression spring which is held in a housing. The spring energizes a fastening plate on which an adhesive band is fastened. The fastening plate is movable in the spring force direction. The housing is arranged in such as way that the energizing force of the spring for pressing the adhesive band to a substrate is not influenced by external force components. The housing is placed on the coated and firmly fitted substrate during the determination process.
