Microprocessor Based Earth Resistance/Ground Resistivity Analyzer (Model DET_µP) can be used to test the effectiveness of the Grounding system, which is an essential part of Electrical System Security to activate the protective devices, if there is an insulation fault. The instrument provides the perfect solution by combining the latest technology into a compact, field rugged and extremely easy to use instrument in performing standard 3/4 Pole Ground Resistance/Resistivity measurements. Before measuring, the instrument identifies and automatically check probe hookup & auxiliary earth electrode resistance to ensure that all the measurements are taken correctly and if any disparity found in Auxiliary Earth Electrode & Lead Resistances, it is well flagged with the results on the screen.
