The Earth Resistance Tester is developed for measuring earth resistance, possibly with the use of a special current clamp for measuring the soil resistivity on LVinstallations according the EN 61577 regulation.
Following tests
2-Point earth resistance
3-Point earth resistance
4-Point earth resistance
Earth resistance by current clamp (‘Utility method)
Soil resistivity (‘Wenner' method)
The integrated ‘Utility'- measurement is especially designed for measuring partial earth resistance at parallel earth connections. This is being done by using a current clamp. This clamp is optional (ERT-a7). The ERT-S has an internal memory of 500 locations for storage of the measured values. These stored values can easily be transferred to a PC (via the RS232 port).
