Product Description

describe:

RDER2000+ Clamp Earth Resistance Tester is widely used in earth resistance measurement of electric power, telecommunication, meteorology, oil field, construction and industrial and electrical equipment. When measuring grounded systems with loops, there is no need to remove the grounding lead or auxiliary electrodes. It's safe, fast and easy to use. This tester can measure ground faults that cannot be measured by traditional methods. It can be used for applications that cannot be measured by traditional methods, because the RDER Series Clamp-On Resistance Meters measure the combined value of ground body resistance and ground lead resistance.

Features

1. Quick self-test, start entering the test immediately.

2. Adopt the most advanced processing algorithm and digital integration technology.

3. The product is light in weight and more in line with the characteristics of handheld devices.

4. New design, 6-button panel operation, better performance.

5. Add sound and light alarm function, with "beep-beep-beep" alarm sound.

6. Increase the function of interference signal identification indicator, with a "beep-beep-beep" indicator.

7. Measuring range: 0.01Ω～1200Ω

8. Store data 99 units. Lower power consumption, the maximum operating current is less than 50mA.
