  • Review of maintenance practices

  • Review of condition monitoring techonologies

  • Principles of vibration; review of basics, waveform, spectrum (FFT), phase, and orbits

  • Understanding signals: modulation, beating, sum/difference

  • Data acquisition

  • Signal processing

  • Vibration spectrum analysis

  • An introduction to time waveform analysis

  • An introduction to orbit analysis

  • Phase analysis: bubble diagrams and ODS

  • Enveloping (demodulation), shock pulse, spike energy, PeakVue

  • Fault analysis

  • Equipment testing and diagnostics including impact testing (bump tests) and phase analysis

  • Corrective action

  • Running a successful condition monitoring program

  • Acceptance testing

  • Review of ISO standards


In this Category II training course, you will learn how to test machines correctly, how to diagnose faults accurately, perform additional diagnostic tests for verification, how to set vibration alarm limits, and how to correct certain types of faults. You will understand what your analyzer settings mean so that you can take the best measurements. You will also learn why the vibration patterns change the way they do and how to use time waveform analysis and phase analysis to verify the fault condition.

This course is designed for those who have been able to master the CAT I basics, but who need to be able to take good data, analyze a range of fault conditions, and understand balancing and alignment.


At least twelve months vibration analysis experience and a thorough understanding of vibration theory and terminology. Eighteen months of vibration analysis experience is required for Category II or Level II certification.
