HIOKI FT6041 4-POLE EARTH TESTER



Grounding means making an electrical connection between an electrical device or a building and the ground underfoot to facilitate the safe use of electricity. Proper installation ensures safe electrical wiring by preventing electric shock and fire. Another purpose of grounding is to avoid power quality issues such as power outages and malfunctions of electrical devices by routing high-frequency noise from the wiring to the ground underfoot. Grounding must be installed in compliance with laws and standards as well as be regularly maintained in order to ensure ground resistance values remain within safe levels.
Ground resistance meters are essential tools to verify that grounding connections have been reliably made ensuring electrical safety in buildings. Since such instruments measure the soil/ground, making contact with mud, water, and other substances in harsh environments is unavoidable. Moreover, extreme temperatures can cause instruments to malfunction or temporarily freeze operations, interfering with work during extended periods of outdoor use. In short, ground resistance meters must withstand harsh environments so that work can be completed efficiently.
Introducing the new Earth Tester FT6041 with extensive measurement functionalities:
  • 4-pole method (Wenner's 4-pole method) - Measure soil resistivity when surveying a grounding design
  • 3-pole method - Precisely measure ground resistance
  • MEC (Measuring Earth with a Clamp) function - Measure ground resistance without disconnecting ground electrodes
  • 3-pole method using 4-terminal measurement - Measure ground resistance values of several ohms or less
  • 2-clamp method - Measure grounding resistance at multiple grounds
  • Low-resistance measurement - Continuity test after ground resistance measurement
Additionally, the FT6041 has the ability to make measurements without shutting off building power and the ability to measure soil resistivity so that ground resistance can be managed more effectively.
