The Megger DCM305E is designed to check earth leakage currents; however 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.
The instrument has six ranges: 6 mA, 60 mA, 600 mA, 6 A, 60 A, 100 A with a minimum resolution of 0.001 mA on the 6 mA range. Either auto or manual ranging can be selected.
Due to the design of the 40 mm jaw the DCM305E allows current measurements on un-insulated conductors and busbars though personal protection against shock should still be maintained.
FEATURES
0.001 mA resolution.
Up to 100 A AC.
TRMS reading.
Low pass filter to aid stability of readings.
Auto, data & peak hold.
40 mm jaw.
Auto power-off (20 min; user-selectable).
