FFT analysis function
Used to investigate the causes of vibration.
Real time FFT analysis with simple condition settings
Waveform recording function(Recorded on SD card)
Data can be saved in CSV format on SD card (50 seconds long)
What is FFT analysis
FFT analysis is a processing method that can extract spectral components contained in waveforms and investigate the causes of vibration by comparing frequency distributions.
SD card
The storage capacity is 2GB, which can store approximately 1000 files. (One file data lasts for 5 seconds)

There are various parameters for describing vibration, generallyThe vibration measuring instrument needs to be switched multiple timesOnly by measuring parameters can multi parameter measurement be completedQuantity.
This vibration instrument only needs to be pressed once to turn onbeginningThe 'key' can measure vibration simultaneouslyAcceleration, velocity, displacement
And diagnosisThe acceleration envelope value used for bearing status,Thus, it can reduce the workload of homework andPrevent missed testing.
Vibration detection
Reference for judging two devices in vibration detection, looking for differences in frequency spectrum and vibration values
Easy judgment of noise, vibration, and abnormal heating
