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 level 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.

My calibration expiry date appears to be wrong

This happens if you do not set the date correctly when you turned the unit

on for the first time during initial setup. Please contact us to resolve the

issue.

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.

I got a LOW Result

A LOW result means that there is very little or no alcohol in your sample.

To comply with the pan-European breathalyser standard, EN16280,

the AlcoSense Excel cannot show a reading when a sample of less

that 0.09mg/L (0.20‰BAC) is detected. This is remove the likelihood

of a false positive result being displayed. Please see the section titled

"Understanding the Results" for more information.

My breathalyser started to do a test by itself and displayed an error

This can happen if the breathalyser is used in a noisy environment over

95dBA. When the unit is slid open to start a test, pressure changes as

a result of loud noises can occasionally cause the unit to think breath is

entering the device, and then show a blow error. If this occurs please

move to a quieter area away from the source of the sound and attempt

the test again.
