ANENG ST211 6000 Counts Digital AC Current Clamp Meter 400A Automatic Range Multimeter with Backlight Voltage Meter Clamp Gauge NCV Test Clamp Ammeter Universal Meter Tester Measuring Temperature / Capacitance/ Diode / AC Current / AC/DC Voltage / Resista Features: Compact size and light weight, portable to carry and easy e in one hand. LCD screen with backlight for clear data display, and data retention function helps check or observe data conveniently. 25mm large jaw opening to measure no touching or interrupting the circuit. Automatic range for intelligent and efficient operation to get more accurate results. 0~400A±(2.5%+8) wide range measurement of AC current, suitable for various wires, convenient & accurate. NCV Non-contact Voltage Detection: If you want to detect whether there is AC voltage or electromagnetic field in the space, you can get the front end of the clamp head of the meter close to the measured object. If there is, a beep will sound and the NCV light will flash. Multifunctional measurements including AC / DC voltage, AC current, resistance, capacitance, frequency, temperature, NCV induction, diode, on-off beep.
