Megger DET2/3 High-Resolution Earth Tester

The DET2/3 is a robust and compact automatic earth (ground) test instrument designed to measure earth electrode resistance and soil resistivity. For use on large or more complex earth systems, which include communications earth systems and difficult test environments, it can be used to test in accordance with BS 7430 (earthing/grounding), BS-EN-62305 (Lightning Protection), BS-EN-50122-1 (Railway Applications), and IEEE Standard 81.

Test frequency, test current, and filtering can be quickly and easily adjusted so that adverse conditions, which can influence the test, can be overcome, and a wide band of test current frequencies, with a resolution of 0.5 Hz, can be used to eliminate errors caused by noise in the earth.

Versatile and Adaptive Testing

One of the standout features of the DET2/3 is its adaptability. With quick adjustments for test frequency, test current, and filtering, this device overcomes adverse conditions that might otherwise skew your results. Its wide range of test current frequencies, adjustable in 0.5 Hz increments, ensures that noise-induced errors are minimized, giving you accurate readings every time.

User-Friendly and Intelligent Design

The DET2/3’s microprocessor-controlled system offers a user-friendly interface, providing excellent error detection and comprehensive test information on a large, clear color display. One of its powerful features is the live trace capability, which graphically displays the noise level from the system under test—a valuable diagnostic tool for expert ground test engineers.

Automatic Frequency Selection for Optimal Results

To further enhance its accuracy, the DET2/3 includes an automatic frequency selection feature. This function scans for the frequency with the lowest noise level and conducts the test at that optimal frequency. The selected test frequency, current level, and enhanced filtering settings are saved in memory for future tests, streamlining your workflow.

Advanced Technology for Comprehensive Data Handling

Equipped with the latest processors and ample internal memory, the DET2/3 allows for immediate calculations of resistivity using the Wenner or Schlumberger methods. It also boasts the capacity to save a full day’s worth of test results. Data transfer is seamless, thanks to the USB flash drive compatibility and direct download capability to a Windows PC running PowerDB™ software.
