We aim to show you accurate product information. \n\nFeatures: \nThe AstroAI True RMS 2000 Counts Digital CLAMP METER is designed to be safely and accurately used by professionals and weekend DIYer’s. It is suitable for commercial and household electrical problems. Advanced features have been provided including AC/ DC Voltage Measurement, AC Current Measurement, Data Hold, Max/MIN Reading, NCV Detection, Flashlight, Diode, Capacitance, Live Wire Test, Resistance Measurement and Audible Continuity Testing.\n\nNote:\nTo measure the current you need to clamp the meter around one of the wires and not the whole power cord. The power cord contains two wires carrying current and ground wire. The current in two wires always flows in opposite directions, so the magnetic fields from two wires cancel each other, therefore the meter reads 0 A.
