OVERVIEW
The ground resistance clamp meter is a comprehensive upgrade from traditional products. It solves the problem of self-inspection for the old model for a long time, and it can be tested when the power is turned on. The new model removes relay self-inspection methods and improves measurement accuracy with advanced algorithms and digital processing technology. The design is more compact and lighter, has an easy-to-handle operation, and adopts a new appearance design. There are only six keys on the panel, which is simple and intuitive. The instrument has a new sound and light alarm function. When encountering abnormalities, it emits a “beep-beep-tidal” warning sound. At the same time, it has an interference signal recognition function, which is also prompted by the sound. The measurement range is expanded from 0.01Ω to 200Ω. It can store 99 sets of data, which is very low power consumption. The maximum current at the start and work does not exceed 50mA. This ground resistance clamp meter suits ground resistance and circuit resistance measurement in many fields, such as electricity, telecommunications, weather, oil fields, construction and industrial electrical equipment. When measuring the grounding system containing circuits, there is no need to disconnect the ground lead or use the auxiliary ground pole to improve safety and speed up the measurement rate. Due to the sum of the geographical and grounding resistance, the grounding failure that is difficult to detect by traditional methods can be detected under certain circumstances.

APPLICATION
Application of Machine Room Earth Resistance Measurement
- In telecommunication systems, machine rooms are often located on the upper floors of buildings, making it challenging to use a meg-ohm meter for measurements. However, RDER clamp meters offer a convenient solution for testing in these scenarios.
Application of Substation Earth Resistance Measurement
- The RDER series clamp meter is ideal for assessing circuit contact and connection conditions. With just one test line, it can efficiently test the connection status of equipment and grounding systems within a substation.
Application of Building Lightning Protection Grounding System Measurement
- When a building’s earth poles are independent, you can measure earth resistance using a clamp meter on any earth pole. Clamping the building’s roof lightning arrester also allows for effective resistance measurement.
- The earth electrode is considered qualified if the measured value is below the allowable threshold. If the value exceeds the allowable limit, the single-earth point method should be used for more accurate measurement
FAQ
Q: What is the function of the earth clamp tester?
A: The earth clamp tester measures the resistance of an electrical grounding system, ensuring it meets safety standards by clamping around a grounding conductor. It verifies grounding effectiveness, preventing electrical hazards and equipment damage.
Q: Can I test earth leakage with a clamp meter?
A: No, a standard ground resistance clamp meter cannot test earth leakage. For this purpose, you need a specialized tool like an Earth Leakage Clamp Meter or Earth Leakage Tester, designed to measure and detect leakage current to the ground.
Q: Which device is used for earth resistance testing?
A: An earth resistance tester or ground resistance tester is used for earth resistance testing.
