Operating Your BACtrack Trace
Performing a Test
Follow these steps to perform an accurate BAC test:
- Important: Wait at least 15-20 minutes after eating, drinking, or smoking before taking a test. Failure to do so can lead to inaccurate results and potentially damage the sensor.
- Press the power button (G) to turn on the device. The device will display a countdown as it warms up (typically 10-20 seconds).
- Once the countdown reaches zero and the display indicates "BLOW", take a deep breath.
- Blow steadily and continuously into the mouthpiece for approximately 5 seconds until the device beeps and clicks, indicating a sufficient breath sample has been collected.
- Your BAC result will be displayed on the LCD screen within seconds.
