Abstract

A method for determining a condition indicator of a water analysis apparatus includes determining a respective parameter value for each of at least two different technical parameters of the water analysis apparatus. A respective deviation value of each of the parameter values is determined with respect to an associated respective parameter reference value for each of the technical parameters. A respective deviation relevance value from each of the deviation values is determined using a respective parameter-specific deviation relevance function for each of the parameter values, the parameter-specific deviation relevance functions being different from each other. Using an indicator function, a condition indicator is calculated from the determined deviation relevance values.
