400 A Mini-Clamp Digital Multimeter
Amprobe AC40C is a clamp-type digital multimeter that offers quick and accurate measurement. The digital multimeter is compact and won't take much space in your tool kit. The compact size of the AC40C meter makes it ideal for taking general measurements on small conductors. The AC40C features AC/DC voltage to 600V, has a 4000-count display, and is CAT III 600 V Rated. Excellent accuracy and resolution offer exceptional performance.
Clamp meters (also called clamp-on meters) measure electrical current without cutting through wires or touching or interrupting the electrical circuit. Available in handheld or benchtop models, clamp meters diagnose problems in electrical equipment, wiring, and power supplies. The meter's current clamp has two jaws that fit around a conductor to take measurements. All clamp meters test for current. Some come with test leads and inputs for measuring voltage, capacitance, and resistance. They display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results and the desired level of protection against transient voltages determine meter choice. Safety ratings are based on the International Electrotechnical Commission's (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.
