VERIFICATION AND
CALIBRATION
The BACtrack 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
immediately by a trained professional.
The product should be recalibrated at least every six to
twelve months. 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/calibration 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.
