Abstract
PURPOSE: To automatically and accurately measure basic frequencies by analyzing vibration waveforms in the relation of frequencies and levels and setting an arbitrary slice level from the outside.
CONSTITUTION: A data input part 5 is connected via data memory part 6 to a data analyzing and processing part 7 and a basic frequency measurement circuit 9 connected with a level setter 9 and a display control unit 10. Then, the vibration waveforms being vibration analysis data 4 of a constant quantity are inputted at a constant sampling period and are stored, after which they are analyzed in the relation of frequencies and levels, and the basic frequency is measured based on the slice level having been set for the results of said analysis, and is displayed in a display device 11. Hence, the basic frequencies of the vibration waveforms are accurately and readily measuted without need for relying upon human manual operations
