- Single-button operation for ease of use.
- Rapid measurement and analysis of breath samples.
- Clear digital display for easy reading of results.
2. Safety Information and Important Notes
Disclaimer: This device is intended for personal use as a guide only. It should not be used to determine whether a person is fit to drive or operate machinery. Legal alcohol limits vary by jurisdiction, and this device does not guarantee compliance with local laws. Always adhere to local regulations regarding alcohol consumption and driving.
- Wait 20 Minutes: For accurate results, wait at least 20 minutes after consuming alcohol, eating, or smoking before performing a test. Residual alcohol in the mouth can lead to inaccurate readings.
- Temperature Range: Operate the device within a temperature range of 0°C to 40°C (32°F to 104°F). Using it outside this range may affect accuracy or cause an "Out C" error.
- Between Tests: If a high alcohol concentration (e.g., 1.00‰ or higher) is detected, wait at least 5 minutes before conducting another test to allow the sensor to clear.
- Avoid Impacts: Protect the device from strong impacts or drops, as this can damage the internal components and affect accuracy.
- Environmental Factors: Do not use the device in environments saturated with smoke or strong fumes, as this can interfere with the sensor.
3. Package Contents
Please check the package to ensure all items are present:
- ACE DA-7100 Digital Breathalyzer
- 2 x AAA 1.5V Alkaline Batteries
- 6 x Sealed Mouthpieces
- Carrying Case (Nylon, black, with zipper)
- Wrist Strap (Grey)
- Multi-language Instruction Manual
4. Setup
4.1. Battery Installation
- Locate the battery compartment on the back of the device.
- Open the battery compartment cover.
- Insert two AAA 1.5V alkaline batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
4.2. Mouthpiece Attachment
- Take one of the sealed mouthpieces from the package.
- Firmly insert the mouthpiece into the designated port on the side of the breathalyzer.
- Ensure the mouthpiece is securely attached to prevent air leakage during testing.
5. Operating Instructions
Follow these steps to perform an alcohol concentration test:
- Power On: Press the ON button located on the front of the device, below the display.
- Warm-up: The device will begin a countdown. This is the warm-up phase for the sensor.
- Prepare to Blow: Once the countdown reaches zero, you will hear two beeps, and the display will show three lines followed by the word "START" flashing. This indicates the device is ready for a breath sample.
- Provide Breath Sample: Take a deep breath. Then, blow continuously and steadily into the mouthpiece for approximately 5 seconds. Moving lines may appear on the display during this process.
- Read Results: After a few seconds, the estimated Blood Alcohol Concentration (BAC) value will be displayed. The result will flash for a short period.
- Automatic Shut-off: The device will automatically power off after displaying the result to conserve battery life.
6. Maintenance
6.1. Mouthpiece Care
- For hygiene, it is recommended to use a new mouthpiece for each test, especially when multiple users are involved.
- Mouthpieces can be cleaned and reused by soaking them in a disinfectant solution (e.g., Amuchina) for about 15 minutes, then rinsing thoroughly and air-drying.
6.2. Battery Replacement
When the "BAt" message appears on the display, the batteries are low and should be replaced immediately with new AAA 1.5V alkaline batteries to ensure accurate readings.
6.3. Calibration
To maintain the high precision of the ACE DA-7100, it is recommended to send the device for professional calibration. This should ideally be done:
- After a maximum of 12 months from the first use.
- After approximately 500 measurements.
Regular calibration ensures the device continues to provide reliable results, as precision may decrease over time with use.
6.4. Storage
Store the breathalyzer in its provided carrying case in a dry place, away from direct sunlight and extreme temperatures. Avoid storing it in environments below 0°C or above 40°C.
7. Troubleshooting
| Problem/Error Message | Possible Cause | Solution |
|---|---|---|
| "Flo" on display | Insufficient or irregular breath sample. | Ensure you take a deep breath and blow continuously and steadily into the mouthpiece for the full 5 seconds when "START" is flashing. |
| "Out C" on display | Operating temperature is outside the recommended range (0°C - 40°C). | Move the device to an environment within the specified temperature range and allow it to acclimate before retesting. |
| "BAt" on display | Low battery power. | Replace both AAA batteries with new 1.5V alkaline batteries immediately. |
| Inaccurate or inconsistent readings |
