Use laminated paper or synthetic canvas to protect the chart from oil, grease, and moisture in the workshop.

When analyzing a spectrum, technicians can quickly cross-reference frequency peaks (e.g., 1 × RPM, 2 × RPM) against the visual illustrations on the chart.

High-frequency energy appears in the ultrasonic range (often tracked via enveloping or PeakVue). No clear peaks in the normal FFT spectrum.

The accuracy of your diagnostic chart depends entirely on the quality of your raw data collection. Follow these procedures to eliminate measurement errors. Triaxial Data Points

What is Vibration Analysis in Predictive Maintenance? - I-care

Characterized by high axial vibration at 1X and 2X running speed , with a 180-degree phase shift across the coupling.

Mount the chart directly next to the vibration data-collector docking stations.
