Feature: 1. Versatile Measurement Capabilities: The ANENG 623 is equipped with a wide range of measurement functions, including AC/DC voltage and current, resistance, capacitance, and temperature. It also includes specialized features such as RPM (revolutions per minute), mS pulse, engine dwell angle, and NCV (non-contact voltage) detection, making it a comprehensive tool for various automotive and electrical applications. 2. Live Wire/Diode Test and Non-Contact Voltage Detection: The multimeter includes live wire and diode testing capabilities, allowing you to quickly and safely check for continuity and identify live wires. Additionally, the NCV (non-contact voltage) detection feature enables you to detect the presence of voltage without making direct contact, enhancing safety and efficiency during electrical work. 3. 5.15-inch 180° Foldable Screen: The multimeter features a large 5.15-inch screen that can be folded up to 180 degrees. This design allows for easy viewing from different angles, ensuring that you can read the display clearly even in tight or awkward spaces. 4. Built-in 3.7V 1800mAh Battery: The multimeter is powered by a built-in 3.7V 1800mAh rechargeable battery, providing long-lasting performance without the need for frequent recharging. This makes it ideal for extended use in the field or workshop, where access to power outlets may be limited. 5. Safety: Full-range overload protection, safeguarding the device from damage due to accidental overloads. This makes it ideal for extended use in the field or workshop, where access to power outlets may be limited.
