👍【Multimeter】A multimeter is a versatile and essential electronic measuring tool used to measure various electrical parameters in a circuit. The name "multimeter" comes from its ability to measure multiple electrical properties, including voltage, current, resistance, capacitance, diode test and continuity.

👍【Activating a Component】Typically refers to the process of turning on or engaging a particular part of the car's system, such as an engine, a fuel pump, or an electrical component. This is often done during diagnostic procedures or repairs to test whether a component is functioning properly. For example, a mechanic might activate the fuel pump to see if it is delivering fuel to the engine, or activate the air conditioning system to check for proper operation.
