Abstract
In a method for storing vibration waveform data sequentially detected by a vibration sensor. The vibration storing method includes detection of a reference level terminal point (P.sub.3) between a preestablished reference level and a vibration waveform. The detected reference level terminal point serves as a trigger. Also, vibration waveform data from a predetermined point (P.sub.0) before a reference level starting point (P.sub.1) to a predetermined point (P.sub.4) after the reference level terminal point (P.sub.3) are stored in a memory. A first preliminary memory and a second preliminary memory are utilized so that the vibration waveform data from those two memories are alternately transferred and stored.
