Why you need this tool Fast, reliable troubleshooting for electrical work in the lab, on the production floor, or at home. Combines multiple tests in one handheld instrument so you can find faults, verify circuits, and confirm safety without switching tools. Non-contact voltage detection reduces the risk of accidental shock when locating live conductors. What it does (key functions) Measures AC and DC voltage and AC current for testing power sources and circuits. Measures resistance and performs continuity tests to find open or shorted connections. Diode test for component verification. Temperature measurement for checking component or surface temperatures. NCV Test (V ~ Alert): non-contact voltage detection identifies live wiring without touching conductors. Large backlit LCD and data hold let you read and capture values clearly in low light. How it solves problems Eliminates time wasted carrying multiple instruments by combining essential electrical tests in one unit. Speeds fault isolation with continuity, resistance, and diode checks; NCV lets you quickly identify live conductors before you probe. Improves accuracy and safety when measuring in dimly lit or cramped spaces thanks to backlight and data hold. Key attributes Function: AC/DC voltage, AC current, resistance, diode, temperature, NCV, continuity. Compatibility: Designed for common electrical testing tasks in laboratories, factories, and homes. Form factor: Handheld instrument for easy one-person operation and portability. Durability and performance: Built for routine field and bench use with stable readings and clear display. Usability: Large LCD backlight and data hold improve visibility and allow convenient recording of results. Practical use scenarios Home appliance repair: Measure outlet voltage, check continuity of wires, and test diodes in circuit boards to identify faults quickly. Factory maintenance: Verify AC current on motors and machinery, use NCV to find energized cables before performing repairs. Laboratory or bench testing: Measure DC voltage and temperature of components during prototyping and verification. What you get A single, multipurpose testing tool that reduces tool changes, improves safety with NCV, and offers clear, holdable readouts for work in any lighting condition.
