TM-510 4000 Counts Multimeter Key benefits — why you need it Fast, accurate troubleshooting: Smart Auto Mode automatically detects AC/DC voltage, resistance, and continuity so you get the right measurement without manual range or mode changes. Safer inspections: Non-contact voltage sensing with visual and audio alerts lets you identify live AC wiring without touching conductors. Durable, everyday tool: Silicone protective cover absorbs shocks and adds insulation, while overload protection helps prevent damage during unexpected voltage spikes. What it does and how it helps Smart Auto Mode: Automatically switches between AC/DC voltage, resistance, and continuity testing for quicker, error-free readings during diagnostics and repairs. Non-contact voltage detection: Detect live AC wires safely with audible and visual warnings. Useful when confirming power before working on circuits or tracing live conductors behind walls. Non-contact AC voltage measurement with overload protection: Measure AC voltage without connecting probes to live wiring; built-in overload protection improves safety and extends instrument life. Protective design: Silicone cover reduces risk of damage from drops and adds an insulating barrier against accidental shocks. Everyday convenience: Data hold to freeze readings, auto-shutdown after 15 minutes (can be disabled), low-battery indicator, backlit HD display for clear readings in dim environments, and a built-in flashlight to illuminate work areas. Compatibility, form and performance Model: TM-510, 4000 counts resolution for clear, reliable readouts. Function set: AC/DC voltage, resistance, continuity testing, non-contact AC voltage detection. Build: Handheld multimeter with silicone protective cover for impact and electrical protection. Performance: Intelligent auto-recognition reduces setup time and errors; backlit HD display improves visibility for accurate interpretation of results. Practical use scenarios Home electrical checks: Quickly verify whether outlets, switches, or circuits are live before replacing fixtures or troubleshooting household wiring. Automotive diagnostics: Test vehicle electrical circuits, check continuity of fuses and wires, and confirm voltages when servicing 12V systems. DIY and hobby projects: Measure voltages and resistance during electronics assembly or repair without constantly switching modes, and use the flashlight/backlight for tighter workspaces. What to expect A compact, easy-to-use multimeter designed for homeowners, car owners, and hobbyists who need a safer, faster way to check electrical systems. Reliable auto-ranging measurements, non-contact live detection with alerts, protective silicone cover, and convenience features that make routine electrical tasks simpler and safer.
