What Makes the Wrindu RD3022E a Professional Multi-Function Ground Resistance Tester?
Wrindu RD3022E earth resistance tester supports 2/3/4-pole testing, soil resistivity & voltage measurement with high accuracy and strong anti-interference performance.
What Core Testing Functions Does the RD3022E Support?
The Wrindu RD3022E is an all-in-one digital earth resistance and soil resistivity tester designed for comprehensive on-site grounding inspection. Unlike single-function meters, it integrates four key testing capabilities: earth resistance, soil resistivity, earth voltage, and AC voltage measurement. It supports 2-wire, 3-wire, and 4-wire (Wenner) testing methods, covering all routine and precise grounding measurement needs for power, construction, and lightning protection projects.

What Accuracy and Measurement Range Can Users Expect?
Precision is the core advantage of the RD3022E for professional field testing. The device delivers high stability across full ranges, with earth resistance accuracy of ±2%rdg±3dgt within 0.00Ω–30.00Ω and wide coverage up to 30.00kΩ. For soil resistivity, it measures from 0.00Ωm to 9000kΩm, meeting requirements for both small building grounding and large substation soil detection.
Equipped with FFT fast Fourier transform and AFC automatic frequency control technology, the tester automatically identifies on-site electrical noise and adjusts test frequency, effectively eliminating interference from nearby transformers, power lines, and industrial equipment.
What Practical Functional Features Optimize Field Testing?
Reliable Data Storage and Export
The RD3022E supports storage of up to 300 sets of test data, with data hold, reading, and overwrite reminder functions. Built-in USB communication allows users to upload, save, and print data via computer, facilitating long-term grounding condition tracking and project filing.
Clear Visual Operation System
It adopts a large LCD white backlight display with bar graph indicators and countdown prompts, ensuring clear visibility in dark outdoor environments. Real-time noise identification symbols also help users judge test validity on site.
