PROBLEM TO BE SOLVED: To prevent a handy type vibration meter with built-in detector from being affected by shaking when the meter is manually operated when vibrations are measured. SOLUTION: In a vibration meter 1, analog signals from a detector 11 are stored in the RAM 10c of a storing section 10 after the data are converted into digital signals. In measurement, the digital signals received during a fixed period of time until now and always stored. When a measurer stores the digital data as vibrational data by operating the meter 1, the measurer presses a storage switch 14a. When the switch 14a is pressed, an MPU 10a selects the digital signal stored before the switch 14a is pressed from the stored digital signals and stores the selected data in the RM 10c as the vibrational data. Therefore, the stored vibrational data do not contain the digital signal stored when the switch 14a is pressed and, even when the meter 1 is shaken by hand when the switch 14a is pressed, the stored data are not affected.
