Megger Earth Leakage Clamp Meter is perfect for identifying and measuring the earth leakage current in a circuit where the RCD keeps tripping out unexpectedly. The measured result will quickly identify whether the earth leakage current present is excessive, causing the RCD to trip or if the RCD itself is over sensitive or faulty. Specially designed to check earth leakage currents, the DCM305E is an efficient and highly versatile instrument. It has six ranges 6mA, 60mA, 600mA, 6A, 60A, 100A with a minimum resolution of 0.001mA on the 6mA range. Its upper range also enables TRMS AC current measurements up to 100A. Additionally, this clamp meter vastly improves measurements on circuits with harmonics/electric noise on the cables using a low pass filter of 50/60Hz. Other key functions include the Data hold feature which aids in measurements where there is a problem with accessibility or poor lighting and the automatic power OFF feature that extends the battery life.
