Description
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.
