Sonel Test Measurement MRU-200 GPS

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
