Important notes on test execution and
self-assessment
After the last sip of alcohol you should wait at least 15
minutes, as there may still be residual alcohol in the
oral cavity, which influences the measurement result.
Also smoking should be avoided before a test, as
cigarette smoke harms the sensor.
For each test you should use a new mouthpiece – not
only for hygienic reasons, but also because an already
used mouthpiece can influence the next measurement
result. The mouthpiece could contain residual alcohol,
which would affect the new test result when the same
mouthpiece is used again (this for example could show
an alcoholization of a person who hasn`t drunken any
alcohol).
If „FLOW" or „Flo" appears on the display, the given
breath sample was insufficient or ended too soon. Blow
into the moutpiece for about 4 seconds constantly
(without a break) – preferably as if you were whistling
without a sound.
If the same person performs 2 tests consecutively,
then wait at least 3 minutes between the two tests, as
a too short waiting time may cause different measure-
ment results. The air exhaled from the lungs is, after a
test, no longer enriched with the same alcohol content
as in the previous test. Therefore, an immediate se-
cond test will indicate a lower test result.
All measured values determined with this breathalyzer
are always indicative and not legally binding.

Why the estimated alcoholization and the measure-
ment result in most cases cannot match
An alcohol test is affected by a lot of different factors
which also affect the test result. Beside the gender,
age, body size and body weight, also the body fat
percentage and the amount of body fluid have a big
influence.
In addition, the general physical and mental state or
the current daily constitution have to be taken into
consideration. Furthermore, the meals eaten before a
breath test (type of content and level of the stomach)
and the intake of medication may influence the
measurement.
Other influencing factors are, of course, the type of
drink (percentage of alcohol content in the beverage
and its carbon dioxide and sugar content), the drinking
rate and the individual subject's duration of alcohol
build-up or degradation in the body.
Some people quickly have a high alcohol content
in the blood, with other people it takes longer until
an alcoholization is detected. About 40-50% of the
consumed alcohol is in the body within 15 minutes,
after 30 minutes it is 65% and after 70 minutes the
previously consumed alcohol is 100% absorbed in the
body. However, it should also be noted that some peo-
ple – partly due to genetic factors – quickly reduce
the alcohol content in the blood, whereas others still
have an increased alcohol content in the blood after a
longer period of time.
