Megger 210400 Megohmmeter, 100 Gigaohms Resistance, 2.5kV, 5 kV Test Voltage

The Megger 210400 series megohmmeter is an analog meter that measures insulation resistance to help reduce shock hazards and downtime on electrical systems that include wires, cables, transformers, and electrical motors. A manual range-selection knob allows the operator to choose the measuring range and the continuously variable test voltage provides highly sensitive insulation resistance readings. The unit tests insulation resistance with low- or high-voltage test voltages. The shielded high-voltage output cable is permanently attached to the unit to avoid damage to the unit. The unit includes circuit breaker protection and redundant grounding connections for increased safety. The 210400 series is commonly used by electricians and electrical contractors.

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 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. Meters measure electrical properties and are safety rated to measure a specific range of results. The range on the meter should be higher than the maximum anticipated value to be measured. 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.
