With the shortcomings of monitoring the current metering devices existing, a new evaluation operation method of energy metering device based on analytic hierarchy arises. The method selects capable of reacting index from aspects of metering devices and uses 1-9 scale method to develop appropriate weighting factor, then proceeds fuzzy quantization operation combined with AHP to constitute status evaluation system. Finally according to the status of the evaluation results, obtain the status of fuzziness of evaluation findings of metering devices. By the case study it shows that this method can identify the target user abnormal condition and returns the probability of abnormal factors.
