4. Operating Instructions
Follow these steps to perform a breath alcohol test:
- Warm-up Phase: After activation, the tester will enter a "warm up" state. A countdown from 10 to 0 will appear on the LCD screen. This indicates the preheating procedure is in progress. Wait for the countdown to complete.
- Prepare to Blow: Once the warm-up is finished, a 10-second countdown for blowing will begin. Position your mouth close to the designated pore (air hole) located on the tester.
- Blow into Sensor: Exhale steadily into the air hole and sensor for approximately 3 to 5 seconds. Ensure a continuous and consistent breath.
- View Results: After the blowing countdown finishes, the display screen will show your test result.
