Breathalyzer
ACE DA-7100
Important Notes
On the Calibration
Each breathalyzer which you buy from ACE Instruments can also be calibrated by ACE Instruments. Of course, we also
calibrate devices which were bought from other contractors, as long as these devices are identical in construction to
the devices sold by ACE Instruments.
You can see the due date of the next calibration on the calibration sticker placed on your breathalyzer. If the sticker is
missing, the calibration is to be done 6 months after the purchase date: e.g. purchase date: 13.05. = next calibration on
the 13.11. and the next on the 13.05. of the following year.
For a calibration service you can send the device to the service address specified at www.alkomat.net.
Why is a calibration necessary?
The calibration is not mandatory, but the accuracy of the sensor installed in the breathalyzer will decrease steadily
without a calibration and additionally guarantee expires, if you don`t pay attention to the calibration ranges.
Which factors influence the measurement accuracy
The more often the device is used the more the zero point is influenced.
The higher the alcohol concentration is, the more the zero point is relocated.
Devices which are used rarely have a decreased sensibility, too.
ACE Instruments recommends using the breathalyzer at least once (1x) a week independently of having drunken
alcohol or not. To maintain the measurement accuracy, the breathalyzer should also be calibrated periodically.
Please also be aware of the several factors of influence on the measuring result
Alcohol amount
Period of the consumption of alcohol
Gender
Age
Weight
Height
Drinking habits
Health state
Vitality of the liver
Size of the lung
Admission of food during the consumption of alcohol
Influence of medicine

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 "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 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 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.
