[Smart Mode]: This smart digital multimeter can automatically measure ac and dc voltage, resistance and continuity with the best resolution. [Open Jaw Design]: The digital multimeter tester with open jaw design for easily measurement in tight space, such as inverter, hub or intensive line. [3-IN-1]: The pocket multimeter can not only be used as a dc ac amp clamp meter, but also can be used as a professional voltage tester. [Amp Automatically Identification]: The digital clamp multimeter can automatically measures dc and ac current with jaw, the measurement can be done manually as well. It support to zero out the readings influenced by earth's magnetic. [Rechargeable]: The digital voltmeter comes with a rechargeable battery and charging cable, ensuring that you never have to worry about running out of power during your measurements.
