MEGGER DET 2/ 2 AUTO EARTH GROUND RESISTANCE TESTER

The Megger® DET2/ 2 Auto Earth Tester is a robust compact instrument designed for measuring earth electrode resistance and soil resistivity. It uses the four terminal method of measurement which eliminates the resistance of the current circuit from the measurement. The circuit design ensures that the resistance of the potential circuit does not affect the measurement during practical testing. The instrument is microprocessor controlled and provides a flexible, ‘ user-friendly’ approach to earth testing by giving good error detection capabilities and full test information on a large easily readable alpha-numeric display. A simple key pad can be used to adjust the test frequency, the test current level and the filtering so that adverse conditions influencing the test may be overcome. The display indicates if: - The noise interference in the soil passing the test current is excessive. The current test spike resistance is too high. The potential test spike resistance is too high. The battery needs recharging. Features: High resolution – 1 mW – ideal for large earthing systems High accuracy for earth electrode and soil resistivity testing Test voltage 50 V max. for safety Rechargeable battery power with long battery life and rapid re-charge A robust, versatile instrument with IP54 protection Filter and high current features to enable valid earth testing in difficult situations
