ISO Category II Vibration Analyst - Intermediate

This course 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 additional 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.

You will come away from the course with a solid understanding of:

Through this Certification Course, participants have the opportunity to accrue 5 Continuing Professional Development (CPD) points.
