Track your B.A.C. – BACTRACK!
InTrOduCTIOn
The BACTRACK® Select S50 Breathalyzer is an alcohol screening
device, used for the detection of alcohol in the breath. The
BACTRACK provides a digital result, displaying an estimate of
the subject’s BAC (Blood Alcohol Content). Before you begin
testing, it is very important to read the entire owner’s manual.
It is also very important to have the instrument calibrated
periodically as recommended on page 12. Failure to do so
may result in readings that are inaccurate.
Alcohol and Its Effects on the Human Body
When a person consumes alcohol, the alcohol is absorbed from
the mouth, throat, stomach and intestines into the bloodstream.
The alcohol in the bloodstream exchanges with air deep in
the lungs. The percent of alcohol in a person’s blood (BAC)
is proportional to the percent of alcohol in a person’s breath
(BrAC). The BACTRACK measures a subject’s deep lung air
alcohol level and converts it to the estimated BAC.
“BAC” means Blood Alcohol Concentration. It is measured in %.
How does alcohol affect my body?
Alcohol is a depressant. It has a relaxing effect on the muscles
in your body. The muscles of your eyes relax and lose focus.
Your eyesight will become fuzzy and you may experience
1
3
double vision. Brain activity is slowed. Your judgment, reflexes,
and coordination are all negatively affected. Some vision
impairments that occur when you have been drinking include:
Narrowing of your field of vision•
Reduction in your depth perception•
Decreased ability to see in darkness•
Increased sensitivity to glare and a longer time for your •
eyes to readjust from the glare
Some mental (brain) impairment can occur when you have been
drinking, including:
Reduced awareness of danger•
Becoming overly confident and reckless•
Difficulty in making decisions•
Reduction in balance•
Slowed reflexes•
Impaired judgment•
Variations among individuals and other factors, such as altitude
and air temperature, affect the degree of intoxication. Some
individuals may become intoxicated at low BAC levels. A low
BAC on a breath alcohol tester does not mean that a person’s
reaction times can respond to any emergency encountered.
Individuals should not drink alcohol and drive or use any
machinery after consuming alcohol.

How does alcohol affect my driving?
We can’t emphasize enough how dangerous it is for you
to drink and drive. Your vision and your brain are the most
important factors in driving safely. If you jeopardize either by
drinking, and then you drive, you are likely to be involved in
a serious or fatal collision.
There is no safe way to drive under the influence of
alcohol. Even one drink can make you unsafe.

* The effects of alcohol intoxication are greatly influenced by individual
variations among users. Some users will be intoxicated at a much lower
BAC than shown above.
**Death can occur at a lower BAC in some individuals.
The generally accepted legal standard for alcohol intoxication in
the United States is 0.08%. However, your driving skills can be
impaired at a level of 0.04% or lower. It is never safe to drink
any amount of alcohol and drive.

can provide inaccurate test results and damage
the sensor.
STEP 1: Insert a disposable mouthpiece.
It is recommended to insert a new
mouthpiece before each test.
STEP 2: Press the POWER button to turn on
the BACTRACK. The total number of tests
performed since the last service is briefly
displayed and then a countdown
sequence begins.

STEP 4: When the countdown reaches zero,
the READY light will flash and two beeps
will sound. Blow hard, continuously, for five
full seconds. While a user is blowing, the
BACTRACK will sound a continuous tone.
Keep blowing until two beeps are heard.
STEP 5: When finished taking a breath
sample, the BACTRACK will circle the outer
LED fields for three seconds while analyzing
the breath sample.
STEP 6: Once the sensor technology has
analyzed the breath sample, the estimated
BAC (Blood Alcohol Content) value is
flashed on the screen.
The test result will be displayed for 10 seconds. Then the
BACTRACK will beep five times before powering off.
If the BAC reading is over 0.05%, the red WARN lamp
will illuminate and a rapid beep alarm will sound.

Understanding BAC Results
The displayed result is an estimate of the test subject’s BAC.
A breath alcohol tester cannot determine the exact BAC in the blood
of the test subject. Correlation between BrAC and BAC depends on
many factors, such as temperature and health conditions. Therefore,
only use this device as a tool to screen for the presence of alcohol.
Many people consider a 0.02% or greater a positive test for alcohol
in “zero tolerance” screening. Most states have 0.08% as the legal
BAC limit for tasks such as operating a motor vehicle. Some states
prohibit driving commercial vehicles or any vessel with a 0.04%
BAC or higher. Many states and countries prosecute individuals for
driving under the influence at any level.
Alerts
Battery Low: The battery power is low.
Please replace the batteries.
Flow Error: The breath sample was not
sufficient. Please repeat the testing process,
ensuring a continuous, 5 second breath
sample.
Time Out: If the user does not blow within
10 seconds, the unit displays [Out] and
shuts down.
Calibration: The unit requires recalibration or
maintenance. Please refer to the Verification
and Calibration section of this manual.

preCauTIOns
Wait at least 20 minutes after drinking, eating or smoking before 1.
testing. Not observing this waiting period can cause inaccurate
readings, damage the sensor, and void your warranty.
Do not blow smoke, food, or liquids into the BACTRACK as this 2.
will damage the sensor.
Do not test in areas with strong winds, smoke, or in an area 3.
where a large amount of alcohol is being consumed.
Replace the two AA batteries when the screen displays [bat].4.
Send your tester in for periodic calibration service as required. 5.
(See calibration).
The BACTRACK Breathalyzer is designed to be used in a tem-6.
perature range of 50-104 °F (10-40 °C). Operation of the unit
in temperature ranges above or below this range may affect the
accuracy of results.
Avoid testing in the presence of any substances that contain 7.
methyl alcohol, isopropyl alcohol or acetone. These substances
may interfere with the results of the test.
Diabetes, a low caloric intake diet, or certain health conditions 8.
may cause a false positive test when there is an increased keytone
concentration in the breath. Consult with a licensed physician to
see if this may apply to you.
Do not use the BACTRACK as a tool to determine whether you 9.
should operate a motor vehicle or equipment, or perform any
other dangerous act.
Do not drink and drive. Always have a designated driver when 10.
alcohol is being consumed.

VerIfICaTIOn and CalIbraTIOn
The BACTRACK Select S50 Breathalyzer is calibrated during
manufacture using advanced alcohol simulation equipment.
Known alcohol concentrations are passed through the sensor
to set baseline values for testing. During testing, the unit
compares users’ breath samples to these baseline values.
The accuracy of breath alcohol testers can fluctuate after six to
twelve months of normal use, depending on the number of tests
performed and operating conditions.
If this product is providing inconsistent test results, is not providing any test results, or provides unusually high or low test results,
the product should be recalibrated by a trained professional.
The product should be recalibrated at least every six to twelve
months depending on frequency of use and operating conditions. We recommend sending the unit in for calibration after
200 tests have been performed, or every 6 to 12 months if
less than 200 tests have been performed. If the product is used
every day, it may need to be recalibrated as frequently as every
month.
Calibration Instructions
Please visit www.bactrack.com or call 877-334-6876 for
information on how to get your BACTRACK Breathalyzer recalibrated.
During recalibration, a professional technician will reset the
sensor baseline values and also perform a full diagnostic check
to ensure the accuracy and reliability of the product.
