Sonel MRU-GPS200 Earth Resistance Tester

Sonel MRU-200-GPS documenting Earth Resistance meter. Fully featured instrument for testing: * earthing resistance using auxiliary electrodes * earthing resistance using auxiliary electrodes and clamp (for measurements of multiple earthing) * earthing resistance using double clamps (for measurement of earthing when it is impossible to use auxiliary electrodes), * impulse earth resistance (without disconnecting measured earthing), * ground resistivity (four spike Wenner method aka Fall of Potential soil resistivity), * current eg leakage current using the clamp or flexible Rogowski coil (both supplied) * measurement of continuity of equipotential bondings and protective conductors (meeting the requirements of IEC 60364-6-61:2000 section 6.12.2) with auto-zero function – with current 200mA. Additionally: * measurement of interference voltage, * measurement of interference frequency, * selection of maximum measuring voltage (25V and 50V) * store up to 1000 results to memory * notes GPS coordinates of test. Automatic report generation of test results once downloaded to PC by USB cable. Online help (wiring diagrams). Supplied with 4 earth spokes, three cable reels, short leads, alligator clips, current CTs, test clamp, structure clamp, software, comms cable, instruction manual.
