RI (Report Indicator)

A report indicator is a device or component used to indicate the status or condition of a system or circuit. It is typically an LED (light-emitting diode) or some other type of light that is activated when a specific condition is met.

Report indicators are used in a variety of applications, such as in power supplies, battery chargers, and audio equipment. For example, a power supply might have a report indicator that lights up when the voltage output is within the specified range. Similarly, a battery charger might have a report indicator that shows when the battery is fully charged.

Report indicators can also be used to indicate error conditions or malfunctions. For example, a computer might have a report indicator that flashes when there is a hardware error, allowing the user to quickly identify the problem.

In addition to LEDs, other types of report indicators include LCD displays, audible alarms, and mechanical indicators such as relays or switches. The choice of indicator will depend on the specific application and the desired level of visibility and user feedback.
