CVSA CVSA Technology and Hardware 2 — Questions and Answers
Question 1: Why is regular calibration of CVSA equipment important before conducting examinations?
- To update the software license
- To ensure accurate and reliable stress measurements (Correct answer)
- To reset the subject database
- To change microphone sensitivity settings arbitrarily
Correct answer: To ensure accurate and reliable stress measurements
Regular calibration ensures the CVSA equipment produces accurate and reliable measurements, maintaining the integrity of all examination results.
Question 2: How should CVSA equipment be stored when not in use between examinations?
- In a humid environment to prevent static buildup
- In a clean, dry location away from extreme temperatures (Correct answer)
- Submerged in cleaning solution overnight
- Exposed to sunlight for natural sterilization
Correct answer: In a clean, dry location away from extreme temperatures
CVSA equipment should be stored in a clean, dry location away from extreme temperatures to prevent damage to sensitive electronic components.
Question 3: What should an examiner do if the CVSA software produces inconsistent or anomalous readings during a test?
- Continue the examination and ignore the anomaly
- Stop the examination and troubleshoot the equipment (Correct answer)
- Manually override the readings in the software
- Immediately conclude the subject is deceptive
Correct answer: Stop the examination and troubleshoot the equipment
If inconsistent readings occur, the examiner should stop and troubleshoot the equipment to ensure the validity and reliability of the examination.
Question 4: Which of the following is a recommended pre-examination equipment check procedure?
- Testing the microphone with a sample voice recording (Correct answer)
- Replacing all battery-powered components before every examination
- Reinstalling the CVSA software before each session
- Replacing the microphone unit before each individual test
Correct answer: Testing the microphone with a sample voice recording
Testing the microphone with a sample voice recording verifies that audio capture is functioning properly before the actual examination begins.
Question 5: How often should CVSA software updates be applied according to best practices?
- Never, as updates can alter calibration baselines
- As recommended by the manufacturer or when updates become available (Correct answer)
- Only when the current version stops functioning entirely
- Every five years regardless of available updates
Correct answer: As recommended by the manufacturer or when updates become available
Following manufacturer recommendations for software updates ensures the system has the latest features, accuracy improvements, and security fixes.
Question 6: What is a key indicator that CVSA hardware may require maintenance or professional assessment?
- The examiner personally prefers newer equipment
- Consistent unexplained anomalies or recurring error readings (Correct answer)
- The equipment is more than one year old
- Another examiner has recommended an upgrade
Correct answer: Consistent unexplained anomalies or recurring error readings
Consistent unexplained anomalies or recurring error readings indicate potential hardware issues that require professional maintenance or replacement evaluation.
