Insufficient sample is a message that occurs if a subject does not provide a consistent breath flow, reaching the minimum sample volume required or sucks back during the breath sample process.

Use proper instructions like, “I would like you to take a deep inhalation, hold it for a moment and then blow at a moderate pace for as long as possible into the mouthpiece.”

If the instrument displays this message even when a consistent sample is submitted, contact Intoximeters technical support for assistance.
