Megger DCM305E 100A TRMS AC Earth Leakage Clamp Meter
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
- Minimum resolution of 0.001 mA on the 6 mA range
- Manual or Auto ranging
- Pre-set leakage limits (0.25, 0.50, 3.5mA) visual and audible indication if limit is exceeded
- 40mm jaw for both insulated and non-insulated conductors
- TRMS readings
- Low pass filter (50/60 Hz) – aids stability of readings
- Auto-backlight, 6000 count display
- Auto, data and peak hold for hard to read measurements
- Analogue bar graph display for trending
