DET2/2 Ground Resistance Tester 
Megger DET2/2 Offers a Wide Range Earth Resistivity Testing
The Biddle Megger DET2/2 Digital Ground Earth Resistance Tester provides a wide resistance range from 0.010Ω to 19.99 KΩ for testing larger or more complex grounding systems and for difficult testing environments, with ±0.5% accuracy and 0.001Ω resolution. Microprocessor control and advanced filtering simplify testing in environments with high levels of interference.
BIDDLE MEGGER DET2/2 Featrures 4-Terminal Earth and Soil Resistivity Testing
The Biddle Megger DET2/2 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 DET2/2 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.
Megger DET2/2 has Microprocessor Intelligent Display Design
The DET2/2's intelligent display indicates the presence of any excessive noise interference in the soil passing the test current, indicates when the current test spike resistance is too high, indicates when the potential test spike resistance is too high and monitors the battery-charge status. The DET2/2's entire testing procedure is accomplished error-free, easier and more efficiently because of these factors.
Biddle DET2/2 has Variable Frequency Test Currents
The DET2/2 offers a wide band of test current frequencies, with a resolution of 0.5 Hz, that may be used to eliminate errors caused by noise in the earth. The chosen test current frequency, test current level and the increased filtering option are stored in memory for use in subsequent tests. The DET2/2's display can be set to show its information in the English, French, German, Portuguese and Spanish. The maximum output voltage is limited to 50 V for safety when performing a test and when re-positioning test spikes. The instrument is auto-ranging relieving the operator of any concern as to which resistance range to use. The low service error meeting an IP 54 environmental specification enable accurate results to be obtained in ‘unfriendly’ testing conditions. Power for the instrument is supplied from a rechargeable lead acid battery which provides 5 hours of life per charge, equivalent to six hundred individual tests lasting 30 seconds each. The DET2/2 is packaged in a robust plastic housing and has its four terminals equipped for both spade and 4 mm connectors, all mounted on the front panel.
DET2/2 Wide Variety of Applications
Megger’s new DET2/2 Earth Tester is a reliable instrument designed for larger or more complex earthing systems, including communications earthing systems and difficult testing environments. It may be used to test in accordance with BS 7430 (1991), the IEE Wiring Regulations and VDE 0413 part 7 (1982). The instrument is suitable for soil resistivity measurements, which are used to establish the optimum electrode design and site, as well as perform archeological and geological investigations. Resistivity tests assist in the design of a correct earth system and avoid the cost of re-working electrode installations. Earth testing kits that include suitable test spikes and test leads, are available separately.
