DIAGNOSTIC APPARATUS AND DIAGNOSTIC METHOD

摘要

This diagnostic apparatus obtains, for each of M devices, deterioration determination data candidates that include second cumulative power consumption amounts for that specific device in all combinations in which that specific device is included (S13), identifies, as deterioration determination data for that specific device, the candidate with the lowest second cumulative power consumption amount among the multiple deterioration determination data candidates (S15), and assesses that the specific device has deteriorated if the deterioration determination data is equal to or greater than a threshold value (T1) (S20).
