Options for Vibration Meter

Spectral Limits Option

The Spectral Limits Option extends the XL2 function range in both, the sound and vibration mode. It adds noise curves, trace capturing, relative curve display and comprehensive tolerance handling for the FFT Analysis and high resolution spectral analysis up to 1/12th octave. The vibration mode is enabled by installing the the vibration option.

XL2 Sound Level Meter

Remote Measurement Option

The Remote Measurement option allows the real-time acquisition of Vibration Meter measurement data directly to a computer application via USB. This allows the user to program unique measurement applications for vibration monitoring or automated measurements. A documented command set for data retrieval via USB is available. The following measurement functions are supported:

  • Vibration Meter/CPB
  • FFT analyzer
  • High resolution spectral analyzer 1/12 Oct + Tol
  • Sound level meter and spectrum analyzer SLMeter/RTA
  • Reverberation Time
  • Audio analyzer RMS/THDN
