The clamp-shaped ground resistance tester is controlled by a microprocessor to accurately detect the ground resistance. It uses a filtering technology to minimize the interference. It is a commonly used and necessary instrument for telecommunication, electric , meteorology, engine room, oil field, electromechanical installation and maintenance as well as industrial enterprise departments using electric .
Features:
Easy to Operate: When measuring ground system with loop, there is no need to disconnect the ground wire without auxiliary electrode, safer and faster.
Clamp Head Design: Using core and winding, stable, precise and strong -interference. Clamp Size: Φ1.26"(32mm), large jaws with double insulation for extra safety.
Data Storage Function: 500 sets of measurement results can be recorded, the "MEM" storage indication, flashing the "MEM" indicating that the storage is full.
Multi Practical Functions: New design, panel operation with 6 buttons, better performance. With real- , data storage, data access, , automatic shutdown and other functions.
Widely Used: It is suitable for measuring all kinds of telecommunications, electric , meteorology, machine room, oil field, distribution lines, tower transmission lines, stations, factory grounding network, rob and other grounding resistance.
