A method for the calibration of a sensor system is provided, the method including use of two calibration media. A high-quality first calibration medium, having a standardized reference independent of the sensor system to be calibrated, is used for a first calibration step in which the sensor system is calibrated and adjusted. A second calibration step immediately follows using a second calibration medium, having a non-standardized reference and being a component of the sensor system, to generate and store measuring signals of the second calibration medium with at least one sensor of the sensor system. Upon subsequent calibrations of the sensor system the second calibration medium is used exclusively so as to generate measuring signals of the second calibration medium with the sensor. If the measuring signals generated in the subsequent calibrations deviate from the stored measuring signals of the second calibration step, an adjustment of the sensor is effected.

Method for calibrating a sensor system

A lighting arrangement comprises a checking device and a method for the control thereof, with a sensor device containing at least one light source, where the at least one light source radiates light with high radiant power which represents a danger to the eyes of operators or service personnel. A housing, which contains the at least one light source and prevents an emergence of light of the light source, is monitored as to whether the housing is open, where the at least one light source with high radiant power is switched off if there is detected upon the monitoring an opening of the housing, which permits an emergence of light of the light source. It is provided here that a lighting arrangement is switched on at the same time or later which has a radiant power not representing any danger to the eyes of operators or service personnel.
