In the world of electrical installations, grounding systems play a critical role in ensuring safety, preventing equipment damage, and protecting users from electric shock. To ensure that a grounding system performs optimally, you need a reliable and accurate testing tool. The Hioki Earth Tester is a professional-grade instrument specifically designed to deliver highly accurate ground resistance measurements with maximum reliability.
What Is an Earth Tester and Why Is It Important?
An earth tester is an instrument utilized to measure ground resistance by assessing the electrical resistance between a grounding setup and the earth around it. It’s an essential tool during the installation and inspection of grounding systems in buildings, industrial facilities, and power distribution networks. Accurate grounding measurements ensure that fault currents are safely discharged into the ground—helping to prevent short circuits, fires, and electric shocks.

How the Hioki Earth Tester Works
Hioki Earth Testers support several ground resistance measurement methods:
Three-Pole Measurement Method
This method is the most frequently employed, involving the measurement of resistance between a grounding electrode and two auxiliary rods. It's ideal for open-field applications such as new construction or power installations.
Two-Pole and Four-Pole Methods
-
Two-Pole: Used when space is limited or only one auxiliary rod can be placed.
-
Four-Pole: Offers higher precision, typically used for geotechnical studies or large-scale grounding systems.
MEC Function (Measurement While Clamped)
The MEC feature allows for ground resistance measurement without disconnecting the grounding electrode—making periodic inspections more efficient and non-disruptive to the system in operation.
