Performing the measurement
Conditions
– Insert a new mouthpiece for each test subject.
– Do not allow any high alcohol concentrations on the sensor, e.g., by rinsing the mouth with
a high proof alcohol shortly before the measurement. Doing this reduces the service life of
the sensor.
– Maintain an adequate distance from mobile phone antennas and transmitting stations.
Requirements of the test subject
– Observe a waiting period of at least 15 minutes after the last oral alcohol intake!
Residual alcohol in the mouth can distort the measurement. Distortions can also occur with
aromatic beverages (e.g. fruit juice), alcoholic mouth sprays, medicines and drops, and
after burping and vomiting. Also observe a waiting period of at least 15 minutes in these
cases. A mouth rinse with water or non-alcoholic beverages does not replace the waiting
period!
–
The device can detect residual mouth alcohol during the delivery of the breath sample, if
this option is activated. If residual mouth alcohol is detected, the measurement is aborted
and a relevant message is displayed.
–
The test subject should breathe normally and steadily prior to the sampling.Rapid inhalation
and exhalation through the mouth should be avoided.
– The test subject must be able to produce the required minimum breath volume (default set-
ting 1.2 L). During testing, the breath flow must fall within a preset minimum blowing period
(default setting 2 seconds).
