The Megger DET2/2 digital ground resistance tester provides a wide resistance range from 0.010 Ω to 19.99 kilohms for testing larger or more complex grounding systems and for difficult testing environments, with ±0.5% accuracy and 0.001 Ω resolution. Microprocessor control and advanced filtering simplify testing in environments with high levels of interference.

The DET2 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 Megger DET 2/2 is built into a robust plastic case and has its four terminals, equipped for spade or 4 mm connectors, mounted on the front panel.

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.
