What is the correct input for gender on the instrument?

• A. Male is default
• B. F for female, male is default
• C. M for male
• D. Other

Answer: (B)

The instrument uses a gender setting to apply the appropriate breath-to-blood partition ratio in the BAC calculation. It comes with male as the default, so you only change it when the subject is female. Entering F for female switches to the female partition ratio, giving a more accurate result for that subject. So for a female test subject, the correct input is F; leaving it as the default would apply the male ratio.
