摘要

Device for testing a sheet metal section (12) before marking the section comprises an illuminating unit (22), a sensor unit (24), an evaluation unit (26) and an input unit (28). The illuminating unit and the sensor unit interact with each other during operation so that the illuminating unit illuminates a defined surface section of the sheet metal section with light and the sensor unit detected the entire intensity of the light reflected by the surface section (14) of the sheet metal section. Preferred Features: The sensor unit detects the whole sheet metal section being tested and the illuminating unit illuminates a narrow strip of the sheet metal section.
