OVERVIEW
The RD3000B ground earth resistance tester was developed based on the latest lightning protection ground resistance detection standards. It is suitable for multi-scenario measurements and can accurately measure ground resistance, soil resistivity, ground voltage, and AC voltage. The instrument has a 20mA test current output capability, integrates digital and microprocessing technology, and supports precise 4-wire, 3-wire, and simple 2-wire methods for measuring ground resistance. By introducing FFT (Fast Fourier Transform) and AFC (Automatic Frequency Control) technology, the tester can automatically identify interference and optimize the measurement frequency, effectively reduce the impact of interference, and ensure the accuracy of ground resistance measurement values. Its anti-interference ability and environmental adaptability are remarkable, and the repeated test results show high consistency. It can maintain high precision, stability, and reliability for a long time. It is widely used in related parameter measurement in power, telecommunications, meteorology, oil fields, construction, lightning protection, and industrial electrical equipment.
