The Megger MOM2 series digital microhmmeter measures resistance in circuit breaker contacts, bus-bar joints, and other high-current links. The meter is autoranging and digital for safety and ease of use. The unit stores up to 190 test results for download to a PC via Bluetooth download. Measures resistance from 0 to 1,000 megaohms. The unit has a DualGround measurement function, which increases test safety by grounding both sides of the test object throughout the test. The unit produces high-current test charges using an ultra capacitor. The LED display combines analog arc response and a dual digital display. The unit is Ingress Protection (IP) 54 rated for protection against dust and splashing water. The MOM2 series is used by electricians and electrical contractors.

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 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.
