AstroAI 2000 Counts TRMS Clamp Meter
The 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.
Note: To 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.
The NCV function can test the voltage without contact. When the Meter senses a weak AC signal, the green indicator light will be on and the buzzer will emit a slow, audible beep. When the Meter senses a strong AC signal, the red indicator light will be on and the buzzer will emit a quick beep.
