Drill: name the fault, make the call

A new spectrum every time, drawn the way AMS draws it. Read the header, run the glance routine, pick the fault and the action. Aim for 85% on both before you trust yourself on a real one. Score is kept on this phone/computer only.

Cases are weighted toward what you meet most on pump stations: normal, unbalance, misalignment, bearings, vane pass. Electrical cases show a high-resolution zoom because they cannot be seen at route resolution. Amplitudes are illustrative; the pattern is the lesson.
