Method for testing an electrode arrangement for generating a non-thermal plasma, and plasma source having an electrode arrangement of this kind and configured for performing a method of this kind

A method for testing an electrode arrangement (1) for generating a non-thermal plasma, comprising the following steps:

• determining at least one power parameter which characterizes a plasma power of the electrode arrangement (1);
• comparing the at least one power parameter with at least one predetermined target parameter value, and obtaining a comparison result, wherein the at least one predetermined target parameter value of the electrode arrangement (1) is stored with a dependence on at least one operational parameter in a characteristic map, from which the at least one predetermined target parameter value can be read according to the at least one operational parameter, wherein the at least one operational parameter is selected from a group consisting of an ambient temperature of the electrode arrangement (1) and a relative humidity in an environment of the electrode arrangement (1);
• and
• assessing the functionality of the electrode arrangement (1) on the basis of the comparison result.
