Which tool is often used for visual inspection of electrical connections?

A magnifying glass or inspection mirror is specifically designed to enhance visibility for close examination of small components and connections, making it an ideal tool for visual inspection of electrical connections. This tool allows technicians to closely inspect wires, connectors, and solder joints to identify any signs of wear, damage, corrosion, or other issues that are not easily visible to the naked eye.

By using this tool, an inspector can ensure that all connections are secure and in good condition, which is crucial for maintaining the integrity of an aircraft’s electrical systems. The magnification helps in detecting small defects that could lead to larger electrical problems if not addressed.

While a multimeter is essential for measuring electrical parameters like voltage, current, and resistance, it does not provide visual inspection capabilities. An oscilloscope offers waveform analysis for more complex electronic troubleshooting, and a screwdriver is a tool for assembling or disassembling mechanical components rather than inspecting them. Therefore, the magnifying glass or inspection mirror stands out as the correct choice for visual inspection purposes.
