Which action adjusts the minimum level of the airflow indicator?

• A. Adjust the airflow indicator minimum level CCW or CW
• B. Press the test push button
• C. Change the battery
• D. Notify Cognizant Officer

Answer: (A)

The key idea is that the minimum airflow setting is changed by adjusting the indicator’s control knob. By rotating the knob in either direction—counterclockwise or clockwise—you set the threshold at which the indicator will alert. This directly changes the minimum level. Using the test push button only checks operation, not the setting. Changing the battery doesn’t affect the airflow threshold, and notifying the Cognizant Officer is an administrative step, not an adjustment of the indicator.
