Which of the following is a reason the EC/IR II disables?

• A. Battery replacement required
• B. Operator login failure
• C. Printer cartridge empty
• D. Dry gas canister has expired

Answer: (D)

Maintaining valid calibration is essential for accurate, defensible breath test results. The EC/IR II disables when the calibration/dry gas canister has expired because calibration relies on a fresh gas standard; once the canister is past its expiry, the device can no longer guarantee the accuracy of its readings, so it shuts down to prevent giving an invalid result. A depleted battery, operator login failure, or an empty printer cartridge can cause operational issues, but they do not, by themselves, invalidate the test result in the way an expired calibration gas does.
