Sonel MRU-30 Earth Resistance and Resistivity Tester CAT III
Measurements:
- 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),
- ground resistivity (Wenner method),
- continuity of equipotential bondings and protective
- conductors (meeting the requirements IEC 60364) with auto-zero function – with current 200mA.
Additionally:
- measurement of resistance of auxiliary electrodes RS and RH,
- measurement of interference voltage,
- measurement in the presence of interference voltage in the power network
- with frequency 50Hz, 60Hz,
- 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,
- data transmission to the computer (USB),
- indication of battery state.
