Feature: 1. Digital Multimeter: Equipped with AL intelligent automatic mode, the 4,000 count intelligent multimeter allows you to quickly switch between all measurement works, including AC and DC voltage, resistance, and continuity, without the need to choose a mode or range. It makes measurement work simple, fast, and accurate. 2. Non Contact Testing: Fully safe non contact voltage test, light and audio alarm. Time saving and safe. You don't need to connect wires to measure the voltage on AC wires, which makes line maintenance easier. 3. High in Safety: The instrument adopts overload protection measures internally to improve product safety performance and maximize safety. External silicone cover can protecting the multimeter from damage and potential electric shock. 4. Various Functions: Supports data retention, automatic shutdown, low battery indicator light, backlight display, and flashlight. All these convenient functions make the instrument enough to meet the daily use of amateur, owners and so on. Easy to use, enjoy endless DIY fun. 5. With LED Light: Independent LED light, easy to work in the dark. The dashboard can replace the battery by unscrewing the bottom screw, then sliding down the lower shell and replacing it with a new one.
