Sonel MRU-200 Earth Resistance & Impedance Meter
Sonel MRU-200 Earth Resistance & impedance meter.
Sonel MRU-200 Earth Resistance & Impedance Meter is one of the unique meters on the market which uses all the measurement methods.
Sonel MRU-200 Earth Resistance & Impedance Meter possible measurements:
- earth resistance measurment with 2-pole, 3-pole,4-pole method
- impulse earth impedance measurement, three kinds of measuring impulse 4/10μs, 8/20μs, 10/350μs
- earth resistance measurement without disconnecting measured earths (using clamp)
- two clamps earth resistance measurement without auxiliary test probes
- earth resistivity measurement
- continuity measurement
Sonel MRU-200 Earth Resistance & Impedance Meter allows measurements of:
- earth resistance using auxiliary electrodes,
- earth resistance using auxiliary electrodes and clamp (for measurements of multiple earthing)
- earth resistance using double clamps for measuring multiple earthing without underground connections
- impulse earth impedance (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 (meeting the requirements of IEC 60364 - 6 - 61:2000 section 6.12.2) with auto-zero function – with current 200 mA.
- measurement of resistance of auxiliary 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, 60 Hz and 400 Hz (with automatic selection of proper frequency of measuring signal or with manual selection)
- selection of maximum measuring voltage (25 V and 50 V)
- 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 and Bluetooth*
- indication of battery state.
Sonel MRU-200 Earth Resistance & Impedance Meter comes complete with a calibration Certificate Traceable to National Standards when purchased new.
