Utility diagnosing equipment, operational program therefor, and utility diagnosing method

摘要

A utility diagnosing equipment can recognize an abnormality or a normality in a plurality of utilities of an identical type, which would not be recognized when an absolute threshold is set. The equipment accepts state values from the plurality of utilities, sets an average value of the state values of each utility to a proxy value, finds a relative value between the state value of each utility and the proxy value thereof, and displays the relative value for each utility. The relative values of the utilities exceeding a predetermined threshold is highlighted.
