Automatic Multimeter Intelligent Digital Display Multifunctional Maintenance Electrician Special Portable Small Power Meter Features: The intelligent auto mode allows the smart digital multimeter to quickly switch between all measurement tasks, including AC/DC voltage, resistance, and continuity, without requiring manual selection of mode or range. This ensures easy, fast, and accurate measurements. Provides non-contact voltage testing with audible and visual alarms for enhanced safety. No need to connect wires to measure AC voltage, simplifying troubleshooting. Built-in overload protection improves safety performance and helps protect users. The silicone cover helps prevent damage and reduces the risk of electric shock. Supports data hold, auto power-off, low battery indication, backlit display, and flashlight function. These convenient features make it suitable for daily use by hobbyists, car owners, and homeowners. Easy to use for various DIY applications. How to Use: 1. Remove the rubber sleeve from the back of the multimeter, open the battery compartment, insert 2 AAA batteries according to polarity markings, then close the battery cover. 2. Turn on the multimeter, insert the test leads as indicated, and wait for calibration before beginning measurement. 3. Measure AC/DC voltage, resistance, or continuity by inserting the test leads into the multimeter and connecting them to the device under test. The multimeter automatically selects the correct measurement mode. Note: Test leads are not required when using the NCV (Non-Contact Voltage) function.
