About Megger 250202 DET2/2 High Accuracy Configurable
The Megger DET2/2 digital ground resistance meter measures earth electrode resistance and soil resistivity to increase the safety and performance of electrical systems. The unit measures digitally and has manually-selected test current, test frequency, and filtering so that it can be used in noisy environments. The meter uses the four-terminal method to eliminate the circuit current resistance for more accurate measurements. The meter measures earth resistance from 0.01 ohms to 19.99 kilohms, with 1 microhm resolution. The alphanumeric LCD display is 35mm x 130mm and gives both test information and test results. The tester is safety rated to European Standards (IEC/EN) 61010-1. It is also Ingress Protection 54 (IP54)-rated for protection against dust and splashing water. The DET2/2 is commonly used by electricians and electrical contractors to help ensure the safety of electrical systems. Specifications Power supply Rechargeable 12V lead-acid internal battery (installed) Ground resistance range 0.01 ohms to 19.99 kilohms Ground resistance resolution 1 microhm Weight (including batteries) 5kg/11 lb. Safety standards met International Electrotechnical Commission (IEC)/European Standards (EN) 61010-1 Ingress protection (IP) standard met IP54, for protection against dust and splashing water Dimensions 245 x 344 x 158mm/9.6 x 13.5 x 6.25 inches (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. Electrical test meters report electrical circuit properties, such as voltage, resistance, capacitance, and continuity. Available in handheld or benchtop form, they detect electrical problems in equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Single-function meters, such as battery testers and voltage testers, measure one property of a circuit, and multimeters measure multiple properties. Electrical test meters display information either in analog form using a needle that moves on a calibrated scale, or in digital form using digits or a graphic representation on an LCD screen. Meters have electrical properties that are to be measured and the anticipated range of results, and should have a rating that is higher than the maximum value of the anticipated range. An electrical test meter has multiple settings corresponding to potential ranges of values for the properties it can measure. A manual ranging meter requires the operator to scroll through a list of settings until the correct range is reached. An autoranging meter cycles through range settings automatically until it reaches the correct range. 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) 9001:2008 standards. What’s in the Box?
