Description
The Ground Resistance Tester Model 6418 measures ground rod, busbar, and grid resistance and impedance without the use of auxiliary rods. Clamp-on ground resistance testers can be used in multi-grounded systems without disconnecting or de-energizing the ground system under test. The Model 6418 simply clamps around the grounding electrode or conductor and measures the resistance to ground. By performing measurements on intact ground systems, the user also verifies the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured.
The 6418 Ground Resistance Tester performs a high sensitivity measurement function enabling measurement of leakage current flowing to ground or circulating in ground loops from 0.5mA to 20A and resistances from 0.01 to 1200Ω. Battery life information is displayed at power-up and an Auto Power Off power management function is standard. The Buzzer and Auto Power Off features may be disabled at any time. An alarm function and a data storage function are also standard. The alarm settings and stored data are saved when the ground tester is turned off. The rugged Lexan® head and body construction resists breakage.
