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. You will then see the following screen on the left. You will need to

blow for approximately 6 to 8 seconds at a steady pressure (like you're

taking a sigh) so make sure you pace your breath for this. When you

start blowing into the breathalyser the screen will change to the one

in the middle below if the pressure is strong enough, and after 6 to 8

seconds of blowing you will see your result. Keep blowing until you

hear a beep.

If you are not blowing hard enough the left hand screen will continue

to show. If this is the case, stop blowing and start again with a slightly

harder pressure. If you do not blow for long enough or do not blow at

a steady pressure the screen on the right will be shown and you must

try again.

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.
