Earth Leakage Clampmeter


The DCM305E Earth Leakage Clampmeter is designed to determine the earth leakage currents. The upper range enables TRMS AC current measurements of up to 100 A. TRMS meters can measure both pure, undistorted, sinusoidal AC waveforms and non-sinusoidal AC waveforms which can contain pulse trains, triangles, spikes and other ragged waves.


  • 0.001 mA resolution
  • 100 A range for standard AC current measurements
  • Compare feature
  • Low pass filter
  • Analogue bargraph display for trending
  • Auto, data & peak hold
  • Auto back light
  • Auto power off (switchable)
  • TRMS reading

    The DCM305E Earth Leakage Clampmeter can quickly identify whether the earth leakage
    current present is excessive causing the RCD to trip or if the RCD
    itself is very sensitive / faulty. Earth leakage can be the result various
    undetected faults in the installation or a faulty appliance.
    Cable insulation deterioration, cable damage or the ingress of
    moisture into areas where exposed terminals are present may give
    rise to earth leakage current.
