The Megger DCM310-EN digital clamp meter is an average-sensing meter for measuring current in electrical testing applications. It has a clamp with two jaws that can close around an electrical conductor up to 1.06" (27 mm) in diameter to measure current without touching or interrupting the circuit. The maximum or minimum reading mode displays the highest or lowest reading in a session to track a sudden increase or decrease in readings, and the hold function keeps a reading on the display, even after the meter is disconnected. The unit automatically turns off after 30 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced. A finger guard on the body of the meter helps protect fingers from shock. The meter can survive falls of up to 1.2 meters to a hardwood or concrete floor. This average-sensing, or average-responding, meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has a sinusoidal waveform. It has a 2,000-count resolution, meaning that it can display up to 1,999 units (3-1/2 digits) before the operating range needs to be changed. The meter meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category III installations up to 600V, which covers items used with enclosed building circuit installations (such as service panel parts, branch circuits, and fixed installations that are connected directly to a building's AC power supply). The unit comes with a pouch for transporting and storing the meter. Specifications -------------- Maximum alternating current (AC) input 400 amp Power supply 9V PP3 or 6LR61 battery (one, installed) Standards met and certifications International Electrotechnical Commission (IEC) safety standard 61010-1; European Conformity (CE) Weight 8.82 oz./250 g Meter dimensions 7.09 x 2.20 x 1.26 inches/180 x 56 x 32 mm (H x W x D) H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. 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. Megger manufactures equipment for cable fault locating, protective relay testing, telecommunications and data integrity, and power quality testing under multiple brand names, among them Megger, Biddle, States, and AVO. The company, founded in 1889, is headquartered in Dover, England, and meets International Organization for Standardization (ISO) standard 9001:2008.
