Abstract

A method for adjusting, calibrating and/or checking a function of a photometric sensor, which is embodied for measuring at least one measured variable in a medium, wherein the sensor works with at least one measuring wavelength and at least one reference wavelength, comprising the steps as follows: mounting a calibration insert in a receptacle provided therefor at the sensor, adjusting, calibrating and/or performing the function check, and removing the calibration insert, characterized in that the transmittance of light of the measuring wavelength and the transmittance of light of the reference wavelength through the calibration insert are different. The invention relates further to a calibration insert.
