Abstract
A method for operating an optical sensor for measuring a physical quantity with a defined scale value that is subject to a calibration certification. The measurement accuracy of the quantity being measured is dependent on at least one external condition, and a given scale value is used for the measurement according to the desired measurement accuracy. The scale value is appropriately changed when the measurement accuracy changes due to a change of external condition. An optoelectronic sensor has a switching arrangement for changing the scale value. The sensor is more diversified and can cover larger measurement ranges without requiring new certifications or authorizations for the different measurement ranges.
