FFT Analyzer Basic FAQ

By inputting the sensitivity value and physical units using the EU calibration function, the vertical axis of the power spectrum can be directly read as acceleration values. For example, if Accelerometer outputs 1 mV per 1 m/ ^s², you can directly read the vibration acceleration spectrum or overall value as acceleration values simply by inputting the unit: m/ ^s² and calibration value (V/EU): 0.001. Alternatively, if you use a linear spectrum, you can read the values in units of m/ ^s².

(Note) Enter m/ ^s² instead of a superscript to clearly indicate that it is the unit of acceleration.
