Megger DET4 series ground resistance testers include a current measuring function for ART (Attached Rod Technique) testing capabilities. With this added function, on-site grounds can be tested separately without having to remove the utility connection. They also provide stakeless testing capability. This method allows the operator to use the instrument like a clamp-on ground tester in applications where that method is viable, while also being able to operate as a fall of potential tester if required.

The DET4 series can measure resistance from 0.01 ohms to 200 kΩ, a key capability for soil resistivity testing. Also, to allow accurate testing in noisy environments, the instruments are capable of rejecting noise up to 40 V peak to peak.

Applications for the Megger DET4 series ground resistance testers:

  • Primary and secondary electrical grounding systems
  • Utility pole grounds
  • Lightning protection systems
  • Residential grounds
  • Machinery safety grounds
  • Computer and communication system grounds
  • EMI/RFI system grounds
  • Antenna and pedestal grounds
  • CATV system grounds
