Features: Digital Multimeter- Used for detecting the existence of magnetic field, such as computer, phone, microwave oven, refrigerator, cell towers, etc. When the existence of EMF is detected, analog bar flashes and sound alarms. More Test Function - It can also test DC voltage, AC voltage, capacitance, resistance, diode, frequency, room temperature, check continuity and detect live wire. Great home use, car repair, mechanical repair etc. Color LCD Display - 3.5" HD color LCD display with bright backlight for easy reading. 3 Results can be shown the screen, such as voltage, frequency and analog bar. Flashlight brings convenience for operation in dim condition. Automatic Identification - Automatic identification greatly improves your test efficiency. Our smart multimeter can automatically identify the tested parameters and choose the corresponding range. USB Rechargeable & Auto Off - With built-in 800mAh rechargeable battery, this multimeter can be charged via attached type-c charging cable. Automatic power off if no operation within 5 minutes(press and hold power button to cancel auto power off function).
