A constant 30 volt reading on the GMDSS console voltmeter would indicate

• A. A malfunction
• B. Normal operation
• C. Battery fully charged
• D. Low battery voltage

Answer: (A)

A steady 30 V on the GMDSS console voltmeter means the supply voltage is outside the normal operating range for a 24 V system, signaling a fault. GMDSS equipment is designed to run from roughly the nominal 24 V DC supply, with only small fluctuations under load; 30 V is higher than what the system should tolerate, so it points to an overvoltage condition or a fault in the power regulation or measurement circuit. This isn’t typical operation, and it isn’t an indication of a fully charged battery. If you see this, treat it as a malfunction and investigate the power supply, charging regulator, and the voltmeter itself.
