How frequently shall the gauge monitoring the supervisory air pressure, if provided, be inspected to verify that normal pressure is being maintained?

• A. Daily
• B. Weekly
• C. Monthly
• D. Annually

Answer: (C)

Regular verification of the supervisory air pressure gauge is needed to ensure the charged supervisory line stays within its normal range. If the pressure drops, the system may not signal correctly or could lose its readiness to operate, and small leaks or regulator faults can go unnoticed. Monthly inspection strikes a practical balance: it catches gradual pressure losses without the excessive effort of daily checks or the risk of missing issues with yearly checks. Keeping the gauge readable and accessible helps ensure any deviation from normal pressure is detected promptly, preserving the reliability of the supervisory function.
