DUOYI DY4300A LCD Digital Ground Resistance Tester 0-20KΩ Accuracy 0.01Ω /Series Interference Voltage/Soil Resistivity/Frequency
DY4300A 2/ 3/ 4-Wire Digital Earth Resistance Tester
Earth Resistance Measurement & Series Interference Voltage Measurement & Soil ResistivityMeasurement & 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.
Series Interference Voltage (Earth Voltage) Measurement
Series Interference Voltage (Earth Voltage) Measurement Measurements are automatically started during a measurement of earth resistance and earth resistivity , and the results can be checked on the Result display screen. Warning message Voltage High and is displayed on the Main display when the earth voltage (Ust) is high.
2Ω/20Ω Range: Voltage High warning appears when the voltage is 12V or higher.Earth resistance measurement cannot be made when the voltage exceeds 15V.
200Ω~200kΩ Range: Voltage High warning appears when the voltage is 15V or higher. Earth resistance measurement cannot be made when the voltage exceeds 20V.
