Description
Overview
The AEMC 4630 is a digital ground resistance tester designed for performing earth ground resistance and soil resistivity tests. This auto-ranging instrument directly measures from 0 to 2000Ω and automatically selects the optimum measurement range and test current. The tester meets IEC standards for mechanical and electrical safety, and is specifically designed to reject high levels of interference, making it suitable for use in challenging field conditions with high stray currents.
