What is a key benefit of using multimeters in aircraft electrical maintenance?

Using multimeters in aircraft electrical maintenance is crucial because they provide readings for various electrical parameters such as voltage, current, and resistance. This versatility allows technicians to assess the electrical system comprehensively, enabling them to detect issues efficiently and accurately. Unlike devices that can measure only specific parameters, a multimeter's ability to switch between different functions makes it an invaluable tool in maintaining the safety and reliability of aircraft systems. This capability helps in diagnostics, ensuring that all electrical aspects are functioning correctly, which is essential for safe aircraft operation.
