How do you handle situations where electrical test results show unexpected fluctuations?

Sample interview questions: How do you handle situations where electrical test results show unexpected fluctuations?

Sample answer:

  • Investigate the measurement setup: Verify the accuracy of the test equipment, connections, and grounding. Ensure the DUT (device under test) is properly isolated and not influenced by external factors.

  • Review test conditions: Check if the ambient conditions (e.g., temperature, humidity) meet the specified test parameters. Consider any potential environmental factors that could affect the results.

  • Analyze the DUT: Examine the DUT’s design, components, and assembly. Identify any potential sources of instability or anomalies that could lead to unexpected fluctuations.

  • Perform repeat testing: Replicate the test with different equipment or parameters to confirm the consistency of the results. Conduct multiple measurements to establish a trend or pattern in the fluctuations.

  • Consult with design engineers: Seek insights from the team responsible for the DUT’s design. They can pr… Read full answer
