Grounding testing methods
WebApr 4, 2024 · This test method evaluates the accuracy of maps generated by ground or aerial response robots of indoor environments, either in standard apparatuses or of real-world spaces. The operator maneuvers the robot through an environment to collect mapping data. A series of split-cylinder fiducials are positioned throughout the environment. WebThe good news is that Fluke has a family of earth ground testers ranging from the handheld model 1630, which uses the stakeless method, to the model 1625 that can perform these tests using four different methods, including stakeless and the Fall of Potential method discussed above.
