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
