Frequently Asked Questions
Why is using the four-terminal technique essential for the Megger DET4TD2 earth resistance tester?
The four-terminal technique removes the connection and cable resistance from calculations by separating current and voltage paths.
This ensures that in measurements with very low resistance, common in modern earthing systems, the errors from wires are ignored and the final result is completely accurate.
What is the advantage of non-rechargeable batteries in this model?
Non-rechargeable batteries typically have much lower leakage current rates compared to lithium or nickel-cadmium batteries.
This feature prevents unwanted leakage currents in the test circuit, maintaining measurement accuracy in sensitive systems.
Furthermore, these batteries have a longer shelf life and eliminate the need for maintaining charging circuits.
Is this device suitable for testing earthing systems of high-rise buildings?
Yes, due to its high accuracy and ability to eliminate lead errors, this device is ideal for testing earthing systems in high-rise buildings, telecommunication towers, and industrial facilities that require very low ground resistance.
