Earth Clamp Meter

Earth Clamp MeterMRU-200 is the unique meter in the market which uses all measurement methods.Possible measurements:earth resistance measurement with 2-pole,3-pole,4-pole method,Selective earth resistance measurement with clamp,(no influence from parallel earths; no opening of rusty junctions is needed),impulse earth resistance measurement, three kinds of measuring impulse 4/10microsec, 8/20 microsecond, 10/350 microsecond,Two clamp earth resistance measurement without auxiliary test problems,earth resistivity measurement,leakage current measurement,  It allows to take the measurements of: 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(Wenner method)current using the clamp(e.g. leakage) and flexible clamp(Rogowsky coil),measurement of continuity of equipotential bondings and protective conductors with auto-zero function-with current 200mA.Additionally:measurement of resistance of auxillary electrodes RS and RH,measurement of interference voltage,measurement of interference frequency,measurement in the presence of interference voltage in the power network with frequency 16 2/3 Hz, 50 Hz, 60Hz and 400Hz,selection of maximum measuring voltage(25V and 50V)introducing the distance between the electrodes for the resistivity in metres(m) and feet(ft),memory of 990 measurements(10 banks of 99 cells each)Calibration of clamp used,real time clock(RTC)Data transmission to the computer(USB)indication of battery state. Other Models are:MRU 120MRU 105//106MRU 21MRU 20.
