Product Details

■ Product Overview

The group DC resistance tester for grounding conductors is designed in accordance with the “Regulations on Preventive Testing of Electrical Safety Tools and Equipment.” ) Product Overview: Developed to assess the quality of electrical contact between grounding wire lugs and busbar clamps and multi‑strand copper flexible conductors.

This instrument employs the DC voltage–current ratio method and comprises a low-voltage, high‑current constant current source and a measurement system. The current source utilizes advanced switching power supply technology, offering strong anti‑interference performance and excellent stability. The measurement section features an intuitive, high‑brightness digital display, ensuring accurate and reliable readings. , The circuit selection switching operation is flexible and convenient.
