About this articleDC Clamp Meter: Accurately measure AC and DC currents! Also available for AC/DC voltage, frequency, resistance, capacitance, diode, continuity, and temperature testing. True RMS for precise measurements on non-linear loads. This clamp meter is a very useful tool for troubleshooting industrial and household electrical problems. NCV DETECTION FUNCTION: Non-contact voltage detection effectively checks the electrical condition by measuring the strength of the electromagnetic field without touching any wires; when the current clamp detects a weak AC signal, the indicator light illuminates.MULTIFUNCTIONAL: Supports data hold, temperature measurement, auto power off, low battery indicator, and continuous operation buzzer. The high-definition backlit LCD screen and LED flashlight make it easy to use in dark environments.PROFESSIONAL MULTIMETER: Automatic dial selection design and NCV non-contact measurement. HOLD for data hold function, FUNC for function switching, ZERO for DC measurement zero setting.WIDE JAW OPENING: The wide jaw opening measures AC current in conductors without touching or interrupting the circuit. To measure current, you need to clamp the multimeter around one of the wires, not the entire power cord. Its slim and compact size makes it easy to use in tight spaces.
