Features: The instrument of this series is a small handheld professional digital clamp meter featuring stable,highly reliable and anti-drop performance. The circuit design takes LSI double integral A/D converter as its core under the protection of an overload protection circuit, making it a superior and handy instrument. Adopt LCD backlit display, convenient to read data in the dark. It can be used to measure DC/AC voltage, current, resistance, diodes, capacitance, frequency, inrush current, duty cycle and in-circuit continuity test. Specially, it features a max and min value hold function, auto/manual ranging select function and low voltage indicating.
