Important Testing Considerations

- Avoid testing in areas with strong fumes, smoke, or other airborne contaminants.
- Allow at least 2-3 minutes between consecutive tests to ensure sensor accuracy and battery life.
- The device is designed for personal use and should not be used to determine fitness to drive or operate machinery.
