TYPE A1>>>>>>>>>> This is a mini multimeter, which has automatic identification design. Connect the test leads in parallel to the circuit, power supply, tested resistor. The meter automatically identify whether it is AC voltage, DC voltage or resistance, and shows the frequency on the screen. 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. Note: 1. Do not input voltages higher than 500V, showing higher voltage are possible, but it may damage the meter. 2. When measuring high voltage, be careful to avoid electric shock. 3. Disconnect the test leads from the circuit when completed measurement. 4. Due to manual measurement, the size may be slightly different. Thank you for your understanding. 5. Due to different light conditions and different monitors, item color displayed in photos may be showing slightly different from real object.
