The Category-II course spans four days with an additional half day for review and the exam. It is intended for people who have mastered the basics but who need to be able to take good data (and decide how the data collector should be set up), analyze a range of fault conditions and understand balancing and alignment. We teach you to test machines correctly, how to diagnose faults accurately, perform additonal diagnostic tests for verification, how to set vibration alarm limits and how to correct certain types of faults. You will learn what your analyzer settings mean so that you can take the best measurements and you will learn why the vibration signatures change the way they do and how to use time waveform analysis and phase analysis to verify the fault condition.
If you have been performing vibration analysis for more than six months and feel that you have a good understanding of the fundamentals then you are ready to step up to Category II course. (Note that 18 Months experience is required to be certified). Anyone who wants to be capable of confidently diagnosing a wide range of fault conditions, correcting certain conditions, and taking accurate measurements needs to take this course. Many plant sites require contractors to be certified and many employers require employees to be certified.
