Vibration Meter
7. Vibration Meter
The Vibration Option turns the XL2 Audio and Acoustic Analyzer
into a professional vibration meter with broadband measure-
ments and spectral analysis in 1/3 or octave resolution. The
XL2 Vibration Meter determines vibration acceleration, velocity
and deflection with standard-compliant weighting filters in the
frequency range from 0.8 Hz to 2.5 kHz. Detailed recording
of measurement data and audio files allow for comprehensive
evaluation and reporting. In addition, the XL2 Vibration Meter
comes standard with an FFT analysis and an oscilloscope func-
tion. Selectable FFT frequency ranges from 1 Hz to 1.69 kHz
allow a detailed examination of the measured vibrations.
The Spectral Limits Option adds functions to the Vibration Me-
ter including a zoom FFT up to 20 kHz and a 1/12 octave band
analysis from 0.73 Hz to 1.36 kHz. Also, it adds the ability to
record reference spectra and set tolerances for pass / fail qual-
ity control measurements. The Remote Measurement Option
allows the real-time acquisition of measurement data directly
into a computer application via the USB interface. A document-
ed command set is available.
