Green Flashing indicates which condition?

• A. All conditions normal
• B. A fault exists
• C. The most recent measurement exceeded the alarm level
• D. An alarm has occurred in the last 12 hours

Answer: (B)

Green flashing signals a fault exists. In many monitoring systems, a steady green means normal operation, while a flashing green light points to a fault in the instrument, sensor, or its electronics that needs service or calibration. It isn’t tied to a measured value exceeding a limit or to something logged in the past; those situations are typically shown by a different indicator color (like red or amber) or by an alarm history rather than a current status light. So the green flashing is your cue that something is malfunctioning or out of spec and should be checked.
