What is the custom programmed test mode sequence for the Intox EC/IR II?

• A. DAAABBBA
• B. AABAABAD
• C. DAAABABA
• D. BADAAABA

Answer: (C)

Custom programmed test mode on the Intox EC/IR II runs through a fixed diagnostic sequence to validate the device before a real breath test. The correct pattern is D A A A B A B A because it matches the exact order specified by the instrument’s documented diagnostic routine. This sequence ensures the internal checks—such as evaluating the analyzer path, blank checks, and calibration verification—are performed in the proper order. The other strings do not align with the official self-test pattern, so they wouldn’t trigger the intended diagnostic steps.
