ETCR ETCR2100A+ Digital Clamp Ground Earth Resistance Meter Tester 0.01-200Ω
Product Description
ETCR ETCR2100A+ Digital Clamp Ground Earth Resistance Meter Tester 0.01-200Ω
- 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 200Ω 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
- 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
