SHOULD I ATTEND THE ENTRY LEVEL OR ANALYSIS I SEMINAR?

“Should I attend the Entry Level or Level I seminar?”, “Am I ready for Level I?” are common questions for those beginning a new career in vibration analysis.

Analysis Level I assumes and builds on the student having a basic understanding of vibration measurement and analysis.

The following questions are taken from the Entry Level training manual and are designed to help one make the decision.
 

It is recommended that you start with the “Entry Level” seminar if you cannot fully answer 80% of the following questions with confidence:

· What are, and, can I explain each of the 5 steps in most successful PdM programs?

· Can I explain each of the 3 basic characteristics measured in vibration?

· Can I explain the effect that decreasing dynamic force has on amplitude response?

· Can I explain the period of vibration?

· Can I explain the difference between a Natural Frequency and a Resonance?

· Can I explain the difference between a Resonance and a Critical Speed?

· What units are used to express amplitude and why use one over another?

· Do I understand what Phase is and when to use it?

· Can I find and explain each of the basic menu selections in my analyzer?

· Can I explain Transducer Sensitivity and Frequency Range?

· What is a low frequency accelerometer? When do I use it? How do I tell my instrument which accelerometer is connected?

· Can I explain why and when to turn off Sensor Power?

· Do I know when to use Auto Range and why?

· Does a Shear Mode Accelerometer have advantages over Compression Mode? If so, what are they?

· Can I explain the common “Average Types”?

· What are Routes?

· Can I explain why Sidebands appear in a spectrum?

· Can I explain how Sidebands help the analyst?

· Can I explain how a Beat differs from classic Amplitude Modulation?

· Am I familiar with common terms such as Sub-synchronous, Fundamental, Harmonic…?

· Can I explain why most rolling element fault frequencies are Non-synchronous?

· Can I explain what indicates the severity of a gear problem?

· Can I explain why high amplitude at 2X Line frequency indicates an eccentric rotor in an AC induction motor?

· What is the difference between Route Mode and Analysis Mode?

· Can I explain how Dynamic Range affects the reading?
