<p>PROBLEM TO BE SOLVED: To provide a vibration meter that can be easily corrected in time. SOLUTION: The portable type vibration meter 1 provided with a vibration measuring means (detector 20) measuring the vibration of a measuring object, in which an internal clock (clock 14), is provided with a time signal acquiring means (antennas 5a, 6a 7a) acquiring a time signal from an exterior by wireless, and a calibrating means (CPU 2) calibrating the time of the internal clock based on the time signal acquired by the time signal acquiring means. In addition, the time signal acquiring means is provided with a plurality of antennas, receiving means (receivers 5, 6, 7) receiving time signals in a plurality of different frequency bands placed at every antenna, and a switching means (a switch 4) selectively switches one receiving means from among a plurality of the receiving means to output the time signal.</p> |
