1. Introduction
This manual provides essential instructions for the safe and effective operation of your ZBK Professional-Grade Portable Alcohol Breathalyzer. Please read this manual thoroughly before using the device and retain it for future reference. This device is designed to estimate blood alcohol content (BAC) for personal use and should not be used as a sole determinant for operating vehicles or machinery.

- Wait at least 13 minutes after consuming alcohol, eating, or smoking before performing a test for the most accurate results. Residual alcohol in the mouth can lead to inaccurate readings.
- Do not use the device in extreme temperatures or high humidity.
- Keep the device out of reach of children.
- Do not attempt to disassemble or repair the device. Contact customer support if issues arise.

5. Setup
5.1 Charging the Device
Before first use, fully charge the breathalyzer. The device is equipped with a rechargeable lithium battery.
- Connect the provided USB charging cable to the device's charging port.

5.2 Attaching a Mouthpiece (for Accurate Mode)
For the most accurate results, use a clean mouthpiece.
- Select a clean, reusable mouthpiece from the package.
- Gently insert the mouthpiece into the mouthpiece port on the top of the device until it is securely in place.
- Ensure the mouthpiece is firmly attached to prevent air leakage during the test.
6. Operating Instructions
The ZBK breathalyzer offers two testing modes: Accurate Mode (with mouthpiece) and Quick Mode (without mouthpiece).
Image: Two ZBK breathalyzers are shown side-by-side. One demonstrates the "Accurate Mode" with a mouthpiece attached, and the other shows the "Quick Mode" without a mouthpiece, indicating its use for qualitative tests.
6.1 General Testing Procedure
- Preparation: Wait at least 13 minutes after consuming alcohol, eating, or smoking. This allows any residual alcohol in your mouth to dissipate, ensuring a more accurate reading.
- Power On: Press and hold the Power/Test button to turn on the device. The LCD screen will illuminate and display a countdown or warm-up sequence.
- Warm-up: The device will typically undergo a brief warm-up period. Wait for the display to indicate it is ready for testing (e.g., "BLOW" or a similar prompt).
- Blow:
- Accurate Mode (with mouthpiece): Inhale deeply, then blow steadily and continuously into the mouthpiece for 3-5 seconds until you hear a beep or the device indicates the sample is sufficient.
- Quick Mode (without mouthpiece): Inhale deeply, then blow steadily and continuously towards the sensor opening (where the mouthpiece would attach) for 3-5 seconds. Maintain a consistent distance.
- Result Display: After blowing, the device will process the sample. Your estimated BAC result will be displayed on the LCD screen within approximately 10 seconds.
- Power Off: The device will usually power off automatically after a period of inactivity or can be manually turned off by pressing and holding the Power/Test button.
7. Understanding Results
The ZBK breathalyzer displays your estimated Blood Alcohol Content (BAC) as a percentage (e.g., 0.050% BAC) or other units (g/L, mg/L, mg/100mL) depending on the device's settings. The device also uses indicator lights to provide a quick visual interpretation of the results.
Image: Two ZBK breathalyzers illustrate the traffic light indicator system. One shows a green light for a BAC below 0.1, indicating no drinking. The other shows a red light for a BAC of 0.15, indicating alcohol consumption.
Indicator Light Interpretation:
- Green Light: Typically indicates a very low or undetectable BAC (e.g., below 0.03% BAC). This suggests no alcohol consumption.
- Red Light: Typically indicates a detectable level of alcohol (e.g., 0.03% BAC or higher). The specific threshold for the red light may vary, but it serves as a warning that alcohol has been consumed.
Disclaimer: The indicator lights and displayed BAC are estimates. Always adhere to local laws regarding alcohol consumption and driving. Do not drive or operate machinery if you have consumed alcohol.
8. Maintenance
8.1 Cleaning
- Device Body: Wipe the exterior of the device with a soft, damp cloth. Do not use abrasive cleaners or immerse the device in water.
