Earth connecting cable is the connection part of power equipment and grounding grid, in the long running process of power equipment, the joint may be rusty or fractured due to the damp or other factors, lead to earth connecting cable and the main grounding grid connection resistance increases, lead to the equipment in the operation in safe hidden trouble, serious will cause equipment to run no ground connection.
The earth connecting cable continuity tester is suitable for the rapid measurement of the on-resistance between the grounding cable and the grounding grid (or adjacent equipment) of electric equipment, and also for the measurement of the resistance with low resistance value.
1. Adopts the new power supply technology, which can realize the rapid measurement of the ground on-resistance.
2. Large output current, high measurement accuracy, small size, light weight, simple operation, strong anti-interference ability.
3. Perfect protection circuit and the discharge alarm function, reduces the wrong operation, strong reliability.
4. Adopt high speed microcontroller, automatically complete data collection and resistance value display.
5.192*64 large screen LCD display , the outdoor display is clearly visible.
6. Built-in large capacity non-volatile memory, can store 500 sets of measurement data.
7. Built-in USB controller supports U disk storage and can store 10000 sets of measurement data.
8. Built-in high precision real-time clock function: date and time calibration.
