• High resolution of 1 mΩ, ideal for large earth (ground) systems • Versatile tests modes • High accuracy for earth (ground) electrode grid and soil resistivity tests • Rechargeable battery power that can last all day with a fast re-charge (up to 10 hours) • Robust instrument with IP65 protection • Automatic test frequency selection, with filters and high current features • Diagnostic trace display • Data storage • Large colour display that shows numeric and graphical results • Optional earth testing kit (ETK) available 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.
