Automatic Multimeter Intelligent Digital Display Multifunctional Maintenance Electrician Portable Power Meter Features: Intelligent auto mode allows the digital multimeter to automatically switch between measurement functions, including AC/DC voltage, resistance, and continuity testing, without manual range selection. Simplifies measurements for fast, accurate results. Non-contact voltage detection with audible and visual alerts; safe and convenient. Enables quick identification of live circuits without direct contact, improving safety during electrical troubleshooting. Built-in overload protection enhances safety and device durability. Durable silicone cover helps protect against drops and electrical hazards. Includes data hold, auto power-off, low battery indicator, backlit display, and built-in flashlight. Designed for reliable everyday use by DIY enthusiasts, automotive users, and homeowners. How to Use: 1. Remove the rubber sleeve and battery cover, insert two AAA batteries according to polarity markings, then securely replace the cover. 2. Turn on the multimeter and insert test leads as indicated. Allow the device to calibrate before beginning measurements. 3. Measure AC/DC voltage, resistance, or continuity by connecting the test leads to the device under test. The multimeter automatically selects the correct function. Note: Test leads are not required when using the non-contact voltage (NCV) function.
