alcohol intake!
Residual alcohol in the mouth can distort the measurement. Even
aromatic beverages (e. g. fruit juice), alcoholic mouth sprays,
medical juices and drops and, belching and vomiting may result in
false data. Also observe a waiting period of at least 15 minutes in
these cases. Rinsing the mouth with water or non-alcoholic drinks
does not replace the waiting time!


sample is taken. Avoid breathing in and out quickly through the
mouth.


volume of 1.2 l (works setting). For the test, the breath flow must
