Abstract:
A hand-held machine vibration tester comprising:(a) a housing about the size of a small match box to contain an electronic circuit; (b) a vibration probe mounted on the outside surface wall section of said housing; (c) a piezo element mounted to the adjacent, inside surface wall section of said housing with a permanent hardening adhesive to form a buttered joint between the inside housing wall and said piezo element; (d) a weight mounted on said piezo element, with a permanent hardening adhesive to form a buttered joint between said weight and said piezo element; (e) said electronic circuit for controllably electrically coupling the output from said piezo element, to drive an electronic display exposed via said housing; (f) an electrical connection sampling output from said electronic circuit, so that connection can be made to electrical equipment; (g) said electronic display for displaying levels of vibration relating to amplitudes and the corresponding frequencies of mechanical vibration exciting said piezo element; (h) a liquid marking line writing pen body attached rigidly to said housing, so as to not obstruct use of said vibration probe; whereby said pen body can be held urging said vibration probe against a machine surface to test machine vibration level and later said pen body can be held to write data on said machine surface.
