INTRODUCTION

This class is intended for the student who desires an integrated, hands-on approach to vibration analysis. This is an introductory course, however the student will benefit greatly with prior understanding of basic vibration concepts. The class shows the student how to use a machinery analyzer in conjunction with AMS Machinery Manager software to analyze basic vibration defects. This course combines basic vibration analysis and basic machinery analyzer operation into one comprehensive approach to vibration problem solving. Participants will receive a complimentary copy of the Pocket Vibration Analysis Troubleshooter Guide.
