Introduction / Context:
Legible schematics depend on clear labeling. Reference designations, pin numbers, polarity marks, and short notes must be placed where they can be read without ambiguity. The claim suggests this whitespace is typically unnecessary; we evaluate that claim.
Given Data / Assumptions:
- Symbols must carry designators (e.g., R10, C3), pin IDs, and possibly orientation cues.
- The drawing may be printed, viewed on screens, or reduced in size.
- Technicians will use the schematic for assembly, test, and repair.
Concept / Approach:
Reserving whitespace ensures labels do not overlap wires or other symbols. Adequate spacing reduces misreads, speeds troubleshooting, and supports automated optical checks on printed documentation. Compacting symbols without room for identifiers undermines the schematic’s primary purpose—communication.
Step-by-Step Solution:
Place symbols with consistent grid spacing to allocate label regions.Add designators and pin numbers near symbols, avoiding wire crossings.Use page breaks or additional sheets rather than cramming content.Verify readability at expected print scales (e.g., A3 to A4 reduction).
Verification / Alternative check:
Print at target scale and perform a quick review; labels should be readable without magnification.
Why Other Options Are Wrong:
Correct for compact single-sheet designs / Valid only with a separate notes page / Necessary only for connectors: Readability requirements apply to all components and layouts, regardless of sheet count or separate notes.
Common Pitfalls:
Letting autorenamed labels overlap in dense areas.Using tiny text sizes that vanish after printing.
Final Answer:
Incorrect
