Features: 1. Dual Mode: Multimeter supports auto mode and manual mode. Auto mode can automatically measure AC / DC voltage, resistance and continuity. 2. Bright LED Flashlight: LED flashlight lets you test efficiently and comfortably anywhere, indoors and outdoors, day and night. 3. Live / Neutral Wire Check: Safe and easy to distinguish the live / neutral wire by comparing the strength of the detected voltage, the wire that detect the stronger voltage signal is live wire. 4. LCD Display: Greatly enhance the reading experience, the lighted up numbers and letters make it very easy to read, even in bright sunlight or poor light. 5. Easy to use: Insert the red test lead into the "INPUT" terminal, black test lead into the "COM" terminal. The AC and DC voltage, resistance and continuity can be measured directly after startup.
