Description of device and functions
The AlcoQuant® 6020 is a modern breathalyser for determining the alcohol level in the
e piration air (lung air). State-of-the-art technologies for the prevention of faulty
measurements and to ensure ma imum measuring precision are implemented in the device.
To achieve this, the following functions and components are constantly controlled.
•Device temperature
•Sample collection
•Signal generator
•LEDs
•Battery
•Alcohol sensor
•internal memory
•Calibration intervals
These are checked prior to measuring by means of an integrated micro-controller block and
the relevant analysis software.
The AlcoQuant® 6020 contains a special electrochemica
electrochemicaelectrochemica
electrochemical sensor
l sensorl sensor
l sensor, which reacts only to
alcohol. The unique characteristic of this sensor is its specific reaction to alcohol as well as its
long-term stability, facilitating a 6-monthly calibration interval. The influence of other
substances that may be contained in the e piration air, such as acetone, eucalyptol, carbon
dio ide, carbon mono ide (smokers) etc. is negligible owing to the electrochemical
measuring principle applied.
The sample collection system, which has been developed for ma imum precision, makes
short measuring intervals possible, thus facilitating e tremely short waiting periods between
measurements. Thanks to the use of the new, improved ethanol sensor E 100 and the
innovative sample collection system, a high degree of reproducibility of measuring results is
guaranteed.
While a person is blowing into it, the device controls and determines the quantity of e pired
air. This ensures that the sensor receives only deep lung air which reflects the blood alcohol
content correctly.
Another special feature of the AlcoQuant® 6020 is the short time required for it to become
operational.
The intuitive operation of the AlcoQuant® 6020 is menu-controlled by means of three keys.All
displays, device status and error messages appear in clear te t on the illuminated graphic
display. This makes the device self-e planatory and this in turn means that the user is
informed of the current status of the device at all times during operation. This dispenses with
the trouble of looking up and searching for the relevant error codes in the operating
instructions.
The device is equipped with data memory and a serial PC interface. This makes it possible to
printout and transfer measured data which can also be analysed statistically at a later time.
The PC interface also enables the user to perform the entire maintenance, calibration and the
device settings via a convenient PC program. Great store was set on e tremely simple and
user-friendly handling.

Prior to commissioning, check the calibration stickers on the device housing. If the date
shown on the plate has been reached or e ceeded, the AlcoQuant® 6020 must be
recalibrated and/or sent for servicing and should not be used for measuring. Maintenance
and calibration must be carried out by qualified and authorised personnel only.

How to measure in the active operating mode
Measuring in the active device operating mode serves to determine the precise alcohol level
in the e pired air. It is ensured that for this process only deep lung air is delivered to the
sensor. This is necessary because the only clear correlation is between the alcohol content of
deep lung air and the blood alcohol level.

Residual alcohol in the mouth
Residual alcohol in the mouth distorts the measurement. Hence it must be ensured that the
test person has not consumed any alcohol immediately before measuring is carried out.
Waiting time: At least 15 minutes after the last alcohol was consumed.
ATTENTION:
Mouth sprays containing alcohol, medical syrups and drops can cause residual alcohol in the mouth, as can burping and
vomiting. Rinsing the mouth ith ater or non-alcoholic beverages is no substitute for the aiting time!
Tobacco smoke

carried out.
Waiting time: At least 2 minutes after smoking.
Hyperventilation

Hyperventilation
Prior to measuring the test person should breathe normally and calmly and not repeatedly
breathe in or out deeply because the breath alcohol level can be briefly reduced because the
tidal air cools down, thus causing the measuring result to be distorted.

This does not mean that the precise value of the alcohol level of the breath is sought. It is
only to check if there is any alcohol in the ambient air. Any values that vary from zero (0.00)
are an indication that there is alcohol in the ambient air. The e act level of the alcohol in the
