Rated to IP54, these ground testers come in four models. Model DET3TD is a digital, 3-terminal instrument for grounding and bonding tests. Model DET4TD is a digital, 4-terminal model that adds resistivity measurements. The DET3TA is an analog 3-terminal model, and the DET3TC is a new tester that adds a current measuring function for attached rod technique (ART ) testing capabilities, which can reduce testing time by as much as 40%. All instruments include a voltmeter and can measure resistance from 0.01 ohm to 2,000 ohms and earth voltages up to 100V. For noisy environments, the testers can reject noise of up to 40V peak to peak.
