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, without manual range selection. Ensures fast, accurate, and easy measurements. Non-contact voltage detection with audible and visual alerts for enhanced safety. No need to connect wires directly to measure AC voltage, simplifying electrical troubleshooting. Built-in overload protection improves safety performance. Silicone cover helps protect the device from damage and reduces risk of electric shock. Supports data hold, auto power-off, low battery indicator, backlit display, and flashlight function. Designed for convenient daily use by hobbyists, automotive users, and homeowners. User-friendly design ideal for DIY applications. How to Use: 1. Remove the rubber sleeve and open the battery compartment at the back. Insert two AAA batteries according to the polarity markings and securely close the cover. 2. Turn on the multimeter and insert the test leads as indicated. Allow the device to calibrate before beginning measurement. 3. To measure AC/DC voltage, resistance, or continuity, connect 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.
