Identification should include
- verifying the severity of the vibration and the condition in which it is most apparent
- determining vibration specification, if applicable
- performing a visual inspection for missing, loose, or failed components
- demonstrating the use of a vibration meter
- isolating the problem to revolutions per minute (RPM) range, if possible.
