Megger has introduced four ground tester models, comprising the Model DET3TD digital three-terminal instrument for grounding and bonding tests, the Model DET4TD digital four-terminal model, which adds resistivity measurement, the Model DET3TA analogue three-terminal model, and the Model DET3TC, which adds a current-measuring function for Attached Rod Technique testing capabilities. On-site grounds can be tested separately without having to remove the utility connection with the added ART function. These IP54-rated instruments feature a large selector switch, making selection for two-pole, three-pole or four-pole quick to test. They can measure resistance from 0.01 ohm to 2,000 ohms and earth voltages up to 100 V.
