It's a clamp meter, without the clamp! This meter has completely open jaws, making it easier to get a measurement in difficult applications such as cramped electrical cabinets.

The jaws are especially narrow, with just 0.57" (14.5mm) jaw opening for precisely measuring smaller conductors. With the Extech MA160, you'll be able to measure both AC/DC current on a conductor without actually breaking the circuit.

This clamp meter also functions as a basic multimeter: it can test AC voltage to 750V, DC voltage to 1000V, resistance to 60MΩ and capacitance to 60mF. Continuity and diode can also be tested and a built-in non-contact voltage detector can be used to verify the presence of live voltage on a circuit before testing takes place.

Additional functions of this clamp meter include a relative mode for capacitance zero and offset adjustment, 2000 count, 2-level backlit LCD display and a built-in LED worklight (ideal for viewing in dimly lit areas).
