2/3/4 Pole Earth Resistance Voltage Soil Resistivity Tester Meter RS232 UT523A
It used accurate 4-pole, 3-pole and simple 2-pole method to measure earth resistance.
Fast Fourier Transform(FFT) and Auto frequency control(AFC) are integrated into this tester.
So it has unique anti-interference capability and also is more reliable.
