DEVICE AND SYSTEM FOR MONITORING THE FUNCTIONAL STATUS OF A TRIBUNAL AND METHOD OF MANUFACTURING THE SAME

摘要

The invention relates to a standard ring (2) for controlling the conformity of a measuring indicator located on a measuring surface of a tribula for measuring the size of rings intended to be worn on the finger, said standard ring (2). being designed to be threaded on the triboulet until it abuts against said measuring surface and thus surround the latter locally, said reference ring (2) having a mark designed to be found when the standard ring (2) is in position. abutment against said measuring surface, either in spatial correspondence with said measurement indicator to be checked, if it is compliant, or in spatial offset with said measurement indicator if it is not in conformity. Devices and systems for monitoring the functional status of a triboulet.
