The abnormality checked by the controller 13 is correctly diagnosed by the signal analyzer 15, and analysis is performed.

However, when a problem occurs in the equipment while working at a long distance, the signal analyzer 15 is required to check the abnormality of the controller 13, but since the equipment 11 is not installed in the equipment 11, the failed equipment 11 is located at a long distance. When checking, it takes a lot of time according to the business trip, requires an after-sales service personnel who have acquired professional skills, and has had many problems.

Accordingly, an object of the present invention is to provide a remote management apparatus using a commercial communication network that can communicate with each other by wire or wireless by using a communication means between a long distance of the equipment and the signal analyzer.
