Measurement methods
- 3-pole and 4-wire method – measurement of earthing systems using auxiliary probes
- 3-pole method with clamp – measurement of earthing systems with multiple earth electrodes
- Two-clamp method – measurement of earthing system when the auxiliary probes cannot be used
- Soil resistivity – Wenner method
- Resistance of earth connection and equipotential bonding measured using current ≥200 mA with auto-zero function – meets the requirements of EN 61557-4
Additional features
- Measurement current of 200 mA – facilitates earth resistance measurements in difficult areas (sand, stony soil)
- Measurement of resistance of auxiliary electrodes RS and RH
- Measurement of interference voltage
- Measurement in the presence of interference voltage generated by power networks with frequency of 50 Hz and 60 Hz
- Selection of maximum measuring voltage (25 V and 50 V)
- Automatic calculation of soil resistivity in ohm-meters (Ωm) and ohm-feet (Ωft)
- Memory of 990 measurement results (10 banks of 99 cells each)
- Calibration of clamp used
- Real time clock (RTC)
- Data transmission to the computer
- Battery indication
