The Megger DET2/3 is a durable and compact automatic earth (ground) test instrument crafted to measure earth electrode resistance and soil resistivity. It is ideal 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 effortlessly adjusted so that adverse conditions, which can affect the test, can be diminished. The DET2/3 boasts a vast band of test current frequencies, with a resolution of 0.5 Hz, that can be used to eliminate errors caused by noise in the earth.
With its microprocessor controlled system it offers a flexible and ‘user-friendly’ approach to earth tests by the provision of superior error detection abilities and full test information shown on a vivid color display. The DET2/3 can provide a live trace of its measurements, which graphically presents the amount of noise from the system under test - a useful diagnostic tool for the expert earth (ground) test engineer.
The DET2/3 also includes an automatic frequency selection feature that scans for frequencies with the lowest noise level and then runs a test at that frequency. The selected test current frequency, test current level and the increased filtering option are stored in memory for use in subsequent tests.
