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
