MI2124 Universal Precision Grounding Resistance Tester

MI2124 Universal Precision Grounding Resistance Tester——A major breakthrough in grounding resistance testing

In recent years, many users in China have used clamp type resistance meters to measure grounding resistance, but the test results differ greatly from reality. Because the clamp type resistance meter measures the circuit resistance, in some special cases the measurement result may be close to the true value, while in most cases the measurement result is not correct. For example, in the case of a tower with four grounding down conductors, using a clamp type ground resistance meter to test the result shows that the circuit resistance composed of the four grounding down conductors is not the grounding resistance at all. Although the majority of power workers are aware that the test results are inaccurate, they have to adopt this method because it does not require opening the grounding wire and on-site testing is very convenient. Today, a new grounding resistance testing method - the electrode selection method - has been born. This method can accurately measure grounding resistance without disconnecting the grounding wire. It also has the advantages of accurate traditional grounding pile method and convenient clamp method. For grounding resistance testing, choosing the electrode method is of epoch-making significance. To learn more about this method, please request the book "Electrical Testing Theory" from our company. We are pleased to introduce the MI2124 grounding resistance tester, which has the function of selecting electrode method for testing, to our users.

MI2124 Universal Precision Grounding Resistance Tester

It includes three measurement methods:
1: Standard four wire method: The traditional grounding pile method is used to measure the grounding resistance, and the two, three, and four wire methods can be used for measurement,
Can calculate soil resistivity.
2: Double clamp method: No need for pile driving, quick measurement.
3: Electrode selection method: For parallel grounding wires, the grounding of the wire can be accurately measured without disconnecting it
Ground resistance.

MI2124 Universal Precision Grounding Resistance TesterFunction:
