High test current up to 80mA yielding resolution of 0.001Ω on 2Ω range.
Advanced Filtering method (based on FFT Fast Fourier Transform) reduces noise interference for obtaining stable measurements.
Earth resistance measurement with 4, 3 and 2 wires
Earth resistivity tester (ρ) using 4 pole Wenner method
800 Data storage points
Test current frequency in four bands of 94 / 105 / 111 / 128Hz
Earth (Ground) Resistance 200kΩ
Earth Soil Resistivity 200kΩ
“Zero adjust” the Residual Resistance (Rk)
Soil Earth Resistivity is automatically calculated
Distance set within a range of 1.0 to 30.0m at 0.1m steps
Several sub-results and parameters can be shown on the display: Resistance of the Auxiliary Earth Spikes, Frequency of Test Current, Voltage and Frequency of Interference (noise), Residual Resistance Rk, etc.
Memory, recall and download – results via USB adaptor
