Which statement best describes calibration practices for the BAR-97 EIS?

• A. Calibrate every 72 hours or when prompted.
• B. Calibrate only when the system fails.
• C. Calibrate weekly.
• D. Calibrate daily.

Answer: (A)

Regular calibration keeps the BAR-97 EIS readings accurate, ensuring test results reflect true emissions rather than instrument drift. The device is designed to require a calibration about every 72 hours and to prompt you to calibrate if drift is detected or a calibration check fails. This combination maintains accuracy without unnecessary checks, and the prompt ensures you can correct any drift right away. Calibrating only after a failure risks using drifted readings, while daily or weekly calibrations deviate from the intended maintenance schedule. So the best practice is to calibrate every 72 hours or when prompted.
