Ace II Basic plus Bedienungsanleitung Seite 5

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 measurement 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 second 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 measurement 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 gen-
der, 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 alco-
hol 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 people – 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.
