-Measures ground resistance (2- and 3-Point) Fall-of-Potential method and soil resistivity (4-Point)
-Fuse protection of 0.1A, >250V, 0.25 x 1.25" with 30kA Interrupt Capacity
-Both models will perform over 2,000 measurements of the 15-second tests between recharging or battery replacement
-Provides a response time of approximately four to eight seconds for a stabilized measurement
-Step voltage tests and touch potential measurements
-Auto-ranging: automatically selects the optimum resistance range and test current
-Designed to reject high levels of noise and interference
-Extremely simple to operate: connect – press – hold – read
-May also be used for continuity tests on bonding
-Large easy-to-read backlit display
-LED on faceplate informs operator of high input noise, high auxiliary rod resistance and fault connections
-Rugged dustproof and rainproof field case
-Color-coded terminals
-Low battery indication
