Diagnostic Approach
Systematic method:
1. Identify the symptom
2. Note the system state
3. Check each component systematically
4. Form a hypothesis
5. Identify discriminating evidence
6. Confirm or rule out
Key principle: Vacuum systems operate in a domain invisible to the human observer. Every diagnosis depends on instrument readings and systematic reasoning, not direct observation.
