Earth Resistance & Resistivity Tester Earth Resistance Measurements with 4, 3 and 2 Wires Earth Resistivity (ρ) Measurement using WENNER method High test current up to 80mA yielding resolution of 0.001Ω on 2Ω range Warning for excessive noise and high Auxiliary Earth Spikes resistance. Advanced Filtering method (based on FFT Fast Fourier Transform) reduces noise interference for obtaining stable measurements. Large Graphic Display with backlight for readings in poorly illuminated areas. Automatic and Manual selection of the Test Current Frequency in four bands (94/105/111/128Hz). In Automatic mode, KEW4106 will select the most suitable Frequency. Several sub-results 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. Up to 800 measurement results can be saved in the memory and recalled on the display. The stored results can be transferred to a PC using the "KEW Report" software and a USB adaptor (Model 8212-USB) which are included. Robust design with IP54 protectio

Earth Resistivity Measurement ● The earth resistivity measurement is useful for soil surveys to establish the optimum earth electrode system design and site, to avoid extra cost of re-working electrode installations. It can be also suitable for geological investigations. ● Earth resistivity measurement is automatically calculated after having set the distance between Auxiliary Earth Spikes (Wenner method). Measurement Method for Earth Resistivity ( ) [Connection of Auxiliary Earth Spikes and Test Leads] Stick the four Auxiliary Earth Spikes into the ground deeply. They should be aligned at...

*1: Auxiliary earth resistance is 100G with Rk correction *2: Depending on the measured Rg. Interval [a] between auxiliary earth spikes is 1.0-30.0m *3: This instrument is NOT designed to measure line voltages on commercial powers. KEW4106 comes with everything you need for testing the Earth Resistance A full set of accessories is included: four auxiliary spikes, four cable reels and four test leads(Red:40m, Yellow/Black/Green:20m) for Earth and Resistivity measurements. It is also supplied with particular test leads with relative probes and crocodile clips dedicated for simplified...
