Theory & formulas
The wizard uses a simple rule table that scores known links between symptoms and faults. For example, dominant axial vibration points to misalignment and a peak at one speed points to resonance.
Scores are not probabilities; they set the order in which to start measuring. A firm diagnosis comes from spectrum, phase and, where needed, envelope analysis.
Frequently asked questions
Does the wizard give a firm diagnosis?
No. It ranks likely causes from symptoms. Several faults can produce the same symptom, so a firm diagnosis needs vibration measurement.
