👍The P100 Pro probe is a handheld electrical testing tool used to diagnose and troubleshoot automotive electrical circuits. It can be used to test for voltage, resistance, and continuity, and can help identify problems such as bad grounds, short circuits, and open circuits.

👍【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.

【Unique Design & Easy to Use】The automotive circuit tester designs with a large alligator clip and two sharp stainless steel probes for one hand easy operation, it can detect hard-to-reach narrow areas and pierce wire. The test light has special shell, mini size, durable ABS material, a top-quality 45-inch silicone wire with sturdy, heat-resistant, high-tensile strength. You can take this mini light tester anytime anywhere.

【LED Digital Display & Bidirectional Voltage Test】The light tester comes with bright LED digital voltage display and can read out volt accurately and quickly, can be clearly seen during the day and night. Connecting a large alligator clip or a second probe to either negative or positive ground, red light indicates positive polarity and green light indicates negative polarity.

【Three Working Modes】Electric test pen designs with a switch and 12V 5W test light bulb, you can change working modes you want easily. You can choose LED digital display and the bulb work at the same time, or either of them works, to test voltage and accurately diagnosis faulty battery or fuse circuit.
