Manufacturer: Megger Brand: Megger Model: 6111-284

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 th...
