The Megger DET2/3 digital ground resistance tester measures earth electrode resistance and soil resistivity. Four terminal measurements eliminate the resistance of the current circuit from the measurement. As a microprocessor controlled system it is flexible and easy to use, providing excellent error detection and complete test information on a large color display.
Test frequency, test voltage, and filtering adjust easily to prevent adverse conditions from influencing the test. A wide band of test frequencies, with resolution of 0.5Hz, can be used to eliminate errors caused by earth noise. The DET 2/3 includes an automatic frequency selection feature that scans for frequencies with the lowest noise level, running the test at that frequency. Model DET2/3RC offers a remote control feature and GPS.
The DET2/3 is available with the ETK 50C or ETK 100C earth testing kit. The ETK 50C earth testing kit offers an additional MCC1010 current clamp, MVC1010 voltage clamp, calibration checker with clamps, two reels of 50m test cables, two reels of 30m test cables, four test spikes, and two 1.4m leads with connectors and clips.
The ETK 100Cearth testing kit offers an additional MCC1010 current clamp, MVC1010 voltage clamp, calibration checker with clamps, two reels of 100m test cables, two reels of 60m test cables, four test spikes, 100m tape measure, and two 1.4m leads with connectors and clips.
