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.
