Troubleshooting
I have got a positive reading but I haven't drunk any alcohol.
This can be caused by testing within 10 minutes of eating some strong
foods, using dental products, chewing gum or smoking. On some
occasions it can also be caused by the body releasing acetone/keytones
released during the metabolism of acetoacetic acid. This can be increased
with the use of some prescribed medications or certain medical conditions,
most commonly diabetes. A healthy body can also create these substances
occasionally, it is more likely if you are on a low carbohydrate diet such as
the Atkins diet or similar. If you experience this problem please call us.
I'm doing a breath test and I can't get it to work.
This can be because you are blowing too hard, too soft or not for long enough
into the mouthpiece. If you blow incorrectly, the unit will show you a tip
explaining what's gone wrong. If you still experience issues, please call us
for assistance.
I've done two breath tests and got different results.
This is expected for several reasons. The first test is the most accurate, if you
perform a second test within a few minutes of the first test the alcohol levels
in your lungs may not have stabilised after the first test, causing the second
test to give you a different reading. If you have recently drunk alcohol, your
blood alcohol level can also change quickly over the course of a few minutes.
UK law allows for a 15% difference in sequential readings as a result. This is
why you should only use the breathalyser at least 90 minutes after drinking
or ideally, the morning after.
Additionally, this is why you cannot use a human to test the accuracy of two
different breathalysers back to back, you will also expect slightly different
readings for the same reason. It can only be done using approved Breath
Alcohol Simulators.

My unit says "Saturation Lockdown"
This is caused by blowing in an abnormally high leve of alcohol. It is
normally caused by doing a breath test just after sipping an alcoholic drink
and there is residual alcohol left in the mouth. This overloads the sensor
and can make it read inaccurately for a period of time while the sensor
recovers. For your safety the unit stops you from performing further tests
until the sensor has recovered. After the period has expired your unit
should work as usual again.
My unit says "Calibration Expired" or "Calibration Due"
The 12 month calibration interval is about to or has expired. After this
time readings may become unreliable. Please contact us to arrange
re-calibration of the unit, our contact details can be found on the back
cover of the manual.
I've done a lot of tests in quick succession and I've got a strange result
This can be caused by a build-up of breath condensation in the breathalyser
which sometimes cause temporary inaccuracy until it evaporates, this
can affect any breathalyser, including Police breathalysers. To avoid this
leave a minimum of 3 minutes between tests and do not perform more
than 10 tests in one hour, and no more than 30 tests in 24 hours. Always
use a new mouthpiece for each test. If you do experience this problem
the condensation should evaporate within 2 hours at normal room
temperature and the breathalyser will return to normal operation.
