The AEMC analog ground resistance tester performs ground resistance measurement from 0.5 to 1000Ω with speed and accuracy. The Model 3620 features three-terminal operation for fall-of-potential earth/ground resistance, and may also be used for 2-Point tests. The large 3.1" logarithmic scale is easy to read, with a separate marking for 25Ω. A large Press-to-Measure button allows for easy measurements. A manual zero adjust is provided for accurate readings. Color-coded terminals are easy-to-use banana plug inputs and binding posts.
