Measurement Mode
1) Mouth alcohol detection mode*
2) EOB(End-of-Breath) mode**
2) EOB(End-of-Breath) mode**
*Mouth alcohol detection mode: Detects residual alcohol in the mouth and distinguishes it from alcohol measured in deep-lung breath, preventing false readings caused by mouth alcohol
**EOB(End-of-Breath) mode: Analyzes air from the end of the breath to minimize mouth alcohol interference and measure BAC more accurately
**EOB(End-of-Breath) mode: Analyzes air from the end of the breath to minimize mouth alcohol interference and measure BAC more accurately
