Description Technical Info Reviews

Meggers DCM305E Earth Leakage Clamp Meter is ideal for measuring the earth leakage current in a circuit where the RCD is tripping out. The clamp meter will quickly determine if the earth leakage current is causing the RCD to trip, or if it is sensitive or faulty.

The DCM305E features a 40mm jaw and is capable of measuring both insulated and non-insulated conductors. The megger clamp meter also enables TRMS AC current measurements up to 100A and measures pure, undistorted, sinusoidal, and non-sinusoidal AC waveforms which contain pulse trains, triangles, spikes and ragged waves.

Megger DCM305E Key Features

Six ranges: 6 mA, 60 mA, 600 mA, 6 A, 60 A, 100 A
