Engineering Lab Checklists

Use these copyable checklists to reduce mistakes and standardize spectral analysis across your team.

Checklist Library

Vibration Diagnostics

Confirm shaft speed reference and units.
Capture startup, steady-state, and shutdown windows.
Track harmonics (1x, 2x, 3x) and sideband spacing.
Log threshold breach with contextual operating load.

Audio Cleanup

Measure baseline noise floor.
Localize hum frequencies and harmonics.
Test notch bandwidth impact on target signal quality.
Validate perceptual quality after filtering.

Machine Monitoring

Define alert bins per machine type.
Use trend windows instead of single-frame alarms.
Cross-check with temperature/current telemetry.
Record false positives and refine thresholds monthly.
