Megger DCM300E Ground Leakage Clamp Meter, 300 mA, 300A Current

Model: 6111-284   |    Mpn: DCM300E   |    Ean: 0644535954461   |    PartNumber: DCM300E   |   Asin: B005T9E0N0

The Megger DCM300E digital ground leakage clamp meter is an average-sensing meter for measuring alternating current (AC) and for locating ground faults in electrical testing applications. It has a clamp with two jaws that can close around an electrical conductor up to 1.57" (40 mm) in diameter to measure current without touching or interrupting the circuit. The meter's 10-microamp minimum resolution detects small amounts of leaking current in ground faults. The hold function keeps a reading on the display, even after the meter is disconnected. The meter's liquid crystal display (LCD) shows readings in digits and on a bar graph and is backlit to provide readability in low light. The unit automatically turns off after 10 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, and insulation around the jaw helps reduce the risk of short circuiting live conductors. 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 3,200-count resolution, meaning that it can display up to 3,199 units (3-3-1/2 digits) before the operating range needs to be changed. The meter meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category II installations up to 600V, which covers large household appliances and devices connected to a fixed power supply (such as refrigerators and air conditioners), and category III installations up to 500V, 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 300 amp Minimum resolution of AC current measurement 10 microamp Power supply 1.5V LR44 batteries (two, installed) Standards met and certifications International Electrotechnical Commission (IEC) safety standard 61010-1; European Conformity (CE) Weight 4.41 oz./125 g Meter dimensions 7.00 x 2.5 x 0.90 inches/176 x 64 x 23 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.

Ground-resistance meters test the condition of a grounding system, and provide resistivity measurements in ohms. The meters are available in digital, analog, and clamp models. Grounding systems protect people and equipment, and provide a safe path for the dissipation of fault currents, lightning strikes, static discharges, EMI and RFI signals, and interference. Regular testing of a grounding system is important for safety and protection of equipment. For example, corrosive soil with high moisture content can degrade ground rods and connections in existing systems and increase the resistance of the system. Ground-resistance meters are used in conjunction with a variety of testing methods to troubleshoot intermittent electrical problems or as part of a regular maintenance plan.

Ground-resistance meters test the condition of a grounding system, and provide resistivity measurements in ohms. The meters are available in digital, analog, and clamp models. Grounding systems protect people and equipment, and provide a safe path for the dissipation of fault currents, lightning strikes, static discharges, EMI and RFI signals, and interference. Regular testing of a grounding system is important for safety and protection of equipment. For example, corrosive soil with high moisture content can degrade ground rods and connections in existing systems and increase the resistance of the system. Ground-resistance meters are used in conjunction with a variety of testing methods to troubleshoot intermittent electrical problems or as part of a regular maintenance plan.

Megger DET14C Digital Clamp-On Ground Resistance Meter with Data Storage

Model: 1000-761   |    Mpn: DET14C   |    Ean: 0013088353821   |    PartNumber: DET14C   |   Asin: B00883AKHO

The Megger DET14C digital clamp-on ground resistance meter measures ground resistance and current in multi-ground electrical installations and lightning protection systems without needing to disconnect the ground. It has a clamp with two jaws that can close around round cables and rods up to 1.45" (37 mm) in diameter and ground tapes and straps up to 1.96" (50 mm) wide to measure resistance without disconnecting the ground. The meter also provides true RMS (root mean square) measurements of current up to 35 amp to help ensure operator safety during operation. The meter has a user-selectable noise filter to allow measurements to be taken in areas with high amounts of electrical noise. The meter's internal data storage allows multiple results to be compared and tracked over time, and readings are date and time stamped for future reference. An alarm notifies user when user-selected minimum and maximum values for current and resistance are reached or exceeded. The hold function keeps a reading on the display, even after the meter is disconnected. In applications where the conductor is difficult to access, an auto-hold feature allows a reading to be captured without requiring the operator to press the button during measurement. The meter's liquid crystal display (LCD) is backlit to provide readability in low light. The clamp jaws have a smooth surface with no interlocking teeth to help prevent build-up of dirt and residue, which can interfere with measurements. The unit automatically turns off after five minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced. The Megger DET14C meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category IV installations up to 600V, which covers measurements at the source of the low-voltage supply, such as electricity meters and overcurrent protection devices. The meter has a wrist strap and comes with a hard plastic carrying case to protect the meter from damage during transport and storage. A finger guard on the body of the meter helps protect fingers from shock.

Specifications Maximum ground resistance input 1,500 ohms Maximum current input 35 amp Standards met International Electrotechnical Commission (IEC)/European Standards (EN) 61010-1, EN61557, European Conformity (CE) marked, Australia NEC 13177 Power supply 1.5V IECLR6 AA batteries (four, included) Weight 2.17 lb./985 g Dimensions 9.7 x 4.4 x 2.0 inches/248 x 114 x 49 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.

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 LED 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 flip through different 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.
