Important Notice: Designed to measure loop resistance only, not single-point grounding. Users can create an artificial loop near the grounding electrode for testing. Refer to the user manual for detailed instructions
Wide Application: Ideal for measuring grounding resistance in power, meteorology, oilfields, construction, and industrial electrical equipment. No need to break down grounding leads or use auxiliary electrodes for loop system measurements
Advanced Functionality: Measures ground faults undetectable by traditional methods, making it suitable for applications where conventional meters fail. Accurately measures the combined resistance of the grounding body and lead
Measurement Range: Offers a wide measuring range from 0.010Ω to 1200Ω with a high resolution of 0.001Ω. The clamp size is Φ32mm, ensuring versatility in various testing scenarios
Precision Measurement: Utilizes loop resistance measurement, combining voltage and current coils. It measures induced potential and current to calculate resistance using the formula R=E/I for precise results
