Product Description

The Amprobe CT235A current clamp probe measures AC or DC current without touching or interrupting the circuit. The clamp has two jaws that fit around a 1.2" (31 mm) conductor to convert a high-current signal to a low-level millivolt signal so it can be read by a testing device. The zero adjust knob allows the operator to compensate for changes in output voltage due to environmental conditions. The clamp attaches to a compatible testing device, such as a digital multimeter, with a 59" (1.5 m) lead. A finger guard on the body of the meter helps protect fingers from shock. The clamp operates on one 9-volt battery (included). It weighs 0.7 pounds (320 g) and measures 8.66 x 2.2 x 1.2 inches (220 x 55 x 30 mm, H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; and D is depth, the horizontal distance from front to back). It meets applicable European Conformity (CE) directives.

Multimeters are electrical test meters that measure multiple properties of an electrical circuit, such as current, voltage, resistance, capacitance, and continuity. Available in handheld or benchtop models, multimeters diagnose electrical problems in electrical equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Multimeters 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. 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.

Amprobe manufactures electrical testing equipment for commercial, industrial, and home use. The company was founded in 1948 and is headquartered in Everett, WA.
