Waveform and spectrum (FFT)
Natural frequencies
Basic forcing frequency calculations

Basic Vibration Analysis

Overall level measurements
Spectrum analysis:
– Harmonics, sidebands and the analysis process
– Alarm limits, trending and exception reports

Fault Diagnosis

Imbalance, misalignment, looseness, eccentricity, resonance
Defects associated with bearings, gears, belts, electric motors

Data Acquisition

Instrumentation
Transducers and transducer mounting
Measurement point naming conventions
Routes/surveys: Loading and unloading the route
Data collection
Following a route
Repeatable data collection
Test procedures
Observations: utilizing your time effectively in the field
Recognizing bad data
