Reliable Clamp Multimeter with True RMS: Accurate AC/DC voltage current, resistance, capacitance, frequency, temperature, diode, continuity test and non-contact AC voltage detection, the Clamp Meter is fully functional and easy to use. Auto-Ranging with NCV: The meter will automatically select the appropriate auto range; NCV detects the existence of AC voltage on conductors and cables in-wall, troubleshooting electrical problems in a safe and user-friendly way Clamp Measuring: Clamp jaw measures AC current up to 40mm without interrupting the circuit, which makes it much safer to use on mains cables and high current loads in vehicles. Continuity Test & Overload Protection: Designed to Safely and Accurately Confirm the Circuit Electricity with Low Voltage Indication and Overload Protection. Features: Small and portable to carry and use. High Resolution, Large & Clear LCD Screen Improves Visibility. Widely used in your life. Suitable for Electrical Equipment Testing and Maintenance. Note: Battery NOT Included.
