Method for determining the condition of an operating medium in a machine, and device designed to carry out the method

A device for a machine, the device comprising:

• the device, which is configured for carrying out a method to determine a condition of an operating medium in the machine, the method including the steps of:
• supplying the operating medium for the machine to a spectroscopy device coupled to the machine;
• performing a spectroscopic measurement analysis by way of a test radiation of the spectroscopy device;
• determining a spectroscopic measurement result based on the spectroscopic measurement analysis;
• and
• setting the spectroscopic measurement result in relation to a measurement reference, with the result that an evaluable measurement signal is issued, wherein the spectroscopic measurement result is repeatedly determined over a predetermined reference operating period following an initial event with regard to the operating medium specifying a plurality of spectroscopic measurement results assigned to the predetermined reference operating period, and the measurement reference is determined from the plurality of spectroscopic measurement results, and the evaluable measurement signal is repeatedly specified over an operating time of the machine in such a way that a specific condition characteristic for the operating medium can be signaled.
