How to Perform a Breath Test
AlcoSense is a sensitive measurement device. Performing a breath test less
than 10 minutes after drinking risks blowing high levels of alcohol directly from
your mouth into the system causing permanent damage to the sensor and
causing the system to read inaccurately. Blood alcohol levels can rise for up to
90 minutes after drinking, for best results only use after this period and ideally
the morning after. Do not blow directly into the blow hole without a blow tube
– this can damage the sensor and significantly reduce the lifetime of your unit.
1. Slide the AlcoSense open and put a blow tube on the system as shown
in the image below. It is recommended to use a new blow tube for each
test for the most accurate readings and hygiene.
2. The AlcoSense will display two warnings, please read these carefully.
On further tests these warnings can be skipped by pressing the central
button twice.
3. When you start to blow, the screen on the
right will be shown. Blow at a steady pressure
and keep the green pressure bar (top bar) in
the middle. If you blow harder the bar will
go further to the right, if you blow softer it
will go further to the left. The lower volume
bar will start to become more green as the
volume of breath exhaled increases. Keep blowing until it is completely
green. The AlcoSense will then display your reading.

PLEASE NOTE:
Leave a minimum of 3 minutes between tests. Do not perform more than 10
tests in one hour and no more than 30 tests in 24 hours. More frequent testing
can cause a build-up of breath condensation in the breathalyser which can
temporarily affect accuracy until it evapourates.
If you perform sequential tests you may get varying results. This is due to
the alcohol level in your lungs needing a couple of minutes to stabilise after
performing the first test, and the fact your body is constantly processing
alcohol into and out of your blood stream. As a result UK law allows a 15%
difference between two sequential test results.
Blow Coach (Patent Pending)
If you blow incorrectly, AlcoSense Ultra will use
its advanced sensors to display a screen like the
below with a customised message showing why
the test went wrong and how to correct it. Just
press the middle button to restart your test. If
you still experience problems please contact us.
Understanding the Results
AlcoSense Ultra will alert you not to drive from 20% below your selected
drink drive limit. Before using the device, make sure you have set the
correct drink drive limit for your country or region through the Country
feature which can be found at Main Menu > Settings > Country.
You can check the current setting in Main Menu > Info, then scroll down
to "Limit". Drink drive limits do sometimes change, before making a
trip to a different region or country always check the limit with the local
authorities and go to the support section on www.alcosense.com to check
for software updates.
