- Earth resistance measurement with 3-pole,4-pole method.
- Selective earth resistance measurement with clamp (no influence from parallel earths;
- no opening of rusty junctions is needed)
- Continuity of equipotential bondings and protecting conductors.
- Two clamps earth resistance measurement without auxiliary test probes.
- Earth resistivity measurement.
Using the additional Sonel ERP-1 pylon tower testing adapter and the Sonel MRU-120 series of earth resistivity meters makes the measurement of the earth resistance of transmission line pylons and the earth resistance of the pylon tower footings easy to perform.
