DY4300A  2/ 3/ 4-Wire Digital Earth Resistance Tester

Earth Resistance Measurement & Series Interference Voltage Measurement & Soil Resistivity Measurement  & Frequency Fst Measurement

Powerful, high precision and wide application range.

Applicable range: Testing earth resistance on power distribution lines, in-house wiring system and electrical appliances.

Technology:Stable measurement results can be obtained under a noisy environment by introducing the FFT (Fast Fourier Transform) technology.
