Operating instructions

 

 

Electrochemical sensor

 

Operation: 

1. Insert the mouthpiece in the opening on the left side. 

2. Press the Start button. 

  

3. A countdown takes place from 150. 
4. Once "

blo

" is displayed, evenly blow into the 

    mouthpiece until you hear a signal tone. 
    

  If you do not blow within 20 seconds,

 

      the unit automatically switches off.  

5

After the measurement, the result of the breath test is shown  

    for approx. 20 sec. on the display. 
    After approx. 15 seconds, the display becomes dark. By 

    pressing the Start button again,

 the unit prepares 

    for a new test (s. point 3). Another breath test can be 
    performed. 
       

 If the test result is over 0.50‰, the

 

        LCD display illuminated red and "WARN" is displayed. A

 

        warning tone is emitted. 

6. The CA 2020 automatically switches off after  
    approx. 20 seconds. 

"OFF" 

appears in the display and 

    a signal tone can be heard. 
7. Please start at point 1 for more tests. 
 

We recommend waiting at least 2 minutes between each test. 
The device is not designed for a series consisting of more 
than ten consecutive measurements. 

The measuring principle

 

Blood and breath alcohol have a close correlation with 
each other. In the depths of the lungs, in the alveolar, 
blood and breathing air are separated by a thin, gas-
permeable membrane. This is where the gas exchange 
takes place. 

Oxygen is absorbed by the blood 

and carbon

 

dioxide and alcohol, if present, is emitted into the 
breathing air. To obtain this air from the depth of the 
lungs (alveolar air) for the analysis, a specific minimum 
quantity of breathing air must be provided. 
 (10 litres per minute of air volume = 5 seconds of strong 
blowing). 
A correct measurement is only possible if the person 
blows really strongly and sufficient breathing air is 
exhaled.
