Megger DCM300E Earth Clamp Meter

The capabilities of the DCM300E extend to measuring currents of up to 300 A AC, making it a highly versatile instrument capable of taking current measurements in a wide variety of situations and applications. For example, a typical application for the DCM300E would be the measurement of earth leakage current in a circuit where the RCD or GFCI repeatedly trips out. The measured result will quickly identify whether an excessive leakage current is causing the RCD or GFCI to trip, or if the RCD or GFCI itself is faulty.
The DCM300E has 4 ranges: 30 mA, 300 mA, 30 A, and 300 A with a best resolution of 0.01 mA. The analogue-style bar graph of the DCM300E is very useful when monitoring changes, allowing you to easily interpret the rapidly changing graph rather than the digital display. Other key functions include the “Data Hold” feature, which helps you record measurements in areas that are difficult to access or are in poor lighting, and the "automatic power off" feature, which extends the battery life.
