What does Easter egging refer to in troubleshooting?

• A. Taking a Measurement That Makes Sense
• B. A Technique for Calibrating Instruments
• C. A Strategy to Check the Obvious Components First
• D. Taking a Measurement That Makes Zero Sense

Answer: (D)

Easter egging in troubleshooting means using measurements that don’t make sense on purpose to test the reliability of the measurement setup. A reading that makes zero sense is a strong cue that something in the measurement path—such as a wrong range, a bad connection, grounding issues, or a faulty instrument—is corrupting the data rather than the device under test. This helps you quickly separate problems in the measurement system from issues in the device itself, so you can fix the setup before judging the device’s behavior. While taking sensible measurements, calibrating tools, or checking obvious components are useful steps, they don’t actively probe the measurement chain the way a nonsensical reading does.
