Sonel Test Earth Ground Resistance and Resistivity Meter with GPS MRU-200 GPS

Product Highlights THE MRU-200-GPS OFFERS A VARIETY OF MEASUREMENT METHODS FOR GROUND RESISTANCE AND RESISTIVIY. The MRU-200-GPS is the only meter which can perform all ground resistance measurement methods; 2-pole, 3-pole, 4-pole, and impulse earth impedance methods. Ground resistance using auxiliary electrodes, or with electrodes and clamp for measurements in the presence of multiple ground paths Ground resistance using double clamps when it is not possible to use auxiliary electrodes Impulse ground resistance without disconnecting measured grounding Soil resistivity using Wenner method Leakage current using current clamp or flexible Rogowsky probe Measurement of continuity of equipotential bonding and protective conductors (meets IEC 60364-6-61:2000 section 6.12.2) with auto-zero function and 200 mA current Ground resistance measurement, with 2-pole, 3-pole, or 4-pole methods Leakage current measurement Selective measurement with clamp excludes influence from parallel ground points No opening of rusted conductors needed Impulse ground resistance measurement at 4/10 µs, 8/20 µs, or 10/350 µs Two clamps resistance measurement method without auxiliary test probes GPS coordinates of measurement location are stored with test results Resistance measurement of auxiliary electrodes Measurement of interference voltage and interference frequency Measurement in the presence of interference voltages at 162/3 Hz, 50 Hz, 60 Hz, and 400 Hz Automatic or manual selection of frequency of measuring signal Selection of maximum measuring voltage (25 V and 50 V) Distance between the electrodes noted in meters (m) and feet (ft) Memory storage for 990 measurements Calibration information of test clamp(s) Real-time clock USB interface for PC connection Internal battery with indication of state of charge Backlit LCD graphic display Double insulated meets IEC 61010-1 and IEC 61557 standards CAT IV 300 V
