2. Intended Use and Areas of Application

The AlcoQuant 6020 was developed for the rapid and precise determination of breath alcohol concentration and is intended for the following areas:

• Police routine checks
• Correctional facilities
• Occupational safety

3. Device and Function Description

During exhalation by the subject, the AlcoQuant 6020 measures the exhaled volume and takes a sample after 1.2 L (default setting). The AlcoQuant 6020 features a special electrochemical sensor that reacts exclusively to alcohol. The key characteristic of this sensor is its specific response to alcohol and its long-term stability, allowing for a 6-month calibration interval. The influence of other substances that may be present in exhaled air, such as acetone or eucalyptol, is negligible due to the applied electrochemical measurement principle.

The sampling system, developed for highest accuracy, allows for short measurement intervals and thus extremely short waiting times between measurements. The use of the new improved ethanol sensor E 100 and the innovative sampling system guarantees high reproducibility of measurement results. The device incorporates the latest technologies to prevent measurement errors and ensure the highest measurement accuracy, including continuous monitoring of the following functions and components:

• Device temperature
• Sampling
• Signal generator
• LEDs
• Battery
• Alcohol sensor
• Internal memory
• Calibration intervals

The device is equipped with a data memory and a serial data interface (RS232). Data can be transferred to a PC and evaluated using the "Datamanager Alco 60XX" software, including the data cable. Operation is performed via the device's three membrane keys. For hygiene, the membrane keys can be easily cleaned with a damp cloth. All device status and error messages are displayed in plain text on the backlit graphic display.

Powering On:

Press and hold the ON/OFF button for approximately 1 second. The device automatically performs a self-test of its internal functions and components. For approximately 2 seconds during this self-test phase, the device version, software version (Rev x.x0), and the next calibration date are displayed. After approximately 3 seconds, the device is ready for measurement in active mode (green LED blinks every 1.5 seconds, display shows "Start measurement").

Powering Off:

Press and hold the ON/OFF button for approximately 3 seconds. If no measurement or button input is performed within 2.5 minutes, the AlcoQuant 6020 will automatically shut down.

Important Usage Notes:

• Smoking: Smoking in the exhaled air damages or destroys the measurement system. Therefore, it must be ensured that the test subject has not smoked immediately before the measurement. Waiting time: At least 5 minutes after smoking.
• Alcohol in Mouth: Residual alcohol in the mouth falsifies the measurement. Therefore, it must be ensured that the test subject has not consumed any alcohol immediately before the measurement. Waiting time: At least 15 minutes after the last alcohol intake. Alcoholic mouth sprays, medical juices and drops, as well as belching and vomiting can also lead to temporary mouth alcohol. Rinsing the mouth with water or non-alcoholic beverages does not replace the waiting time!
• Hyperventilation: The test subject should breathe normally and calmly before the measurement, and not inhale or exhale deeply multiple times (hyperventilation), as this can temporarily alter the breath alcohol concentration due to cooling of the breath air, thus falsifying the measurement result.

4.1 Active Measurement (Menu Point 1)

Measurement in the active device mode is used for precise determination of alcohol concentration in exhaled air. This ensures that only deep lung air is supplied to the sensor. This is necessary because there is a direct correlation between the alcohol content of deep lung air and blood alcohol content.

Inserting Original Mouthpiece:

Insert an EnviteC mouthpiece into the designated mouthpiece connector of the AlcoQuant 6020. To do this, open the hygienic packaging of the mouthpiece at the perforation and use it as a hygienic contact shield during insertion (see illustration).

Possible Errors – Measurement Interruption:

If the breath flow is interrupted during the blowing process, a long double tone will be heard, and the error message "Blow error" will appear. The blowing process must be repeated.

• A new mouthpiece must be used for each measurement in active mode.
• The blow-off opening must be kept clear during the blowing process, otherwise the measurement value will be falsified.
• If the subject appears conspicuous due to their behavior or alcohol odor despite a zero measurement, the device must be checked by trained service personnel.
• Patients with reduced lung volume may not reach the required exhalation volume of 1.2 L. In this case, perform a measurement in passive measurement mode (without mouthpiece).

Starting Active Measurement:

After switching on, the device automatically switches to active mode, and "Start measurement" appears on the display. The measurement starts automatically with the exhalation of breath.

Blowing Process:

Blow evenly and with sufficient airflow into the device. An exhalation volume of 1.2 liters must be reached.

Acoustic + Optical Signal:

Correct blowing is indicated by an acoustic signal and the blinking yellow LED.

End of Measurement:

The blowing process is complete when no more sound is heard and the yellow LED turns off. The device analyzes and displays the measurement value. Press a button to switch the device back to measurement readiness.

4.2 Passive Measurement (Menu Point 2)

Select ">Passive measurement<". Measurement in passive mode is performed without a mouthpiece and is used to check ambient air or exhaled air, e.g., from unresponsive patients. It exclusively checks whether alcohol is present in the ambient air. A displayed value other than "0.00" is an indication of alcohol in the ambient air.

Measurement Procedure:

Hold the ready device with the blow-off opening (without mouthpiece) close to the area to be measured, e.g., the patient's mouth and nose, for approximately 5-10 seconds (s). Then, trigger the sample by briefly pressing the "Start" button. The sample should be triggered during the patient's exhalation phase.

Results:

• No Alcohol Detected: If no alcohol is detected, a signal tone sounds, and the green LED lights up.
• Alcohol Detected: If alcohol and a measurement value are displayed, a double tone sounds, and the red LED lights up.

Note: Values measured in passive mode do not correspond to the breath alcohol concentration in deep lung air and therefore do not allow conclusions to be drawn about the blood alcohol concentration. The exact breath alcohol concentration of deep lung air can only be reliably determined in active measurement mode.

4.3 Data Memory

The device has a data memory where measurement results are stored. Each measurement performed is automatically saved with date, time, measurement value, and protocol number. The data memory stores 9,999 data sets.

Storage Warnings:

• Reaching 90% of the storage capacity (9,000 measurements) is indicated by the message ">Caution: Memory 90% full<" on the display. This warning must be confirmed by briefly pressing the "OK" button.
• After the 9,999th measurement, the message ">Caution: Memory full<" appears on the display. This message must also be confirmed by briefly pressing the "OK" button. The oldest measurement value will then be automatically overwritten with the new measurement value!

Measurement values stored in the data memory are retained even when the batteries are changed.

5. Maintenance / Device Care

Calibration:

The device must undergo maintenance every 6 months. This includes the following points:

• Calibration of the device
• Check of the proper device functions
• Calibration verification

Maintenance must be carried out exclusively by EnviteC or by service personnel trained by EnviteC.

Cleaning:
