The BACtrack S80 offers several user-adjustable features through Menu Mode. To enter Menu Mode, turn on the BACtrack, and during the countdown hold MODE for 5 seconds.
Units of Measure: By default, the BACtrack will display test results in %BAC, which is the standard in North America and in many other regions. To change to a different unit of measure, press START. You can select Promille (0/00) or mg/L as alternate units of measure.
Audible Warnings: By default, the BACtrack does not sound an audible warning after a specific %BAC result. To set an audible warning after a specific %BAC test result, press START to cycle through %BAC values.
Blow Time: The default blow time is 5 seconds. This longer blowing time generally provides a deep lung air sample and a more accurate test result. To adjust the blow time, press START.
Flow Detection Settings: Use this option to adjust how hard a user is required to blow. Press Start to change the settings.
A single column of lines requires a less forceful breath by the user, whereas three columns require a more forceful breath.
USER activated test mode is a mode where the operator must press Start during a breath sample to activate the pump and perform a test.
