🔍 Key Concepts

• How a vibration meter works (it measures vibration level, not the internal part that is failing) • The difference between symptom (vibration) and specific cause (which part is bad) • Whether a single reading can positively diagnose a specific fault vs just indicate overall condition

💭 Think About

• Ask yourself: Does a basic hand-held vibration meter "know" which internal component is bad, or does it simply show how smooth or rough the machine is running? • Consider which option describes a general operating condition, versus options that name a very specific failed part. • Think about what information you would need to confidently say a bearing, rotor, or stator is bad. Does the question mention any such detailed analysis?

✅ Before You Answer

• Identify which choice refers to a general operating condition and which ones name specific failed components. • Remember that a single vibration reading is usually used to compare against a normal baseline level, not to pinpoint the exact failed part. • Verify which answer choice is about overall vibration/condition rather than diagnosing an exact internal fault.
