This GFL-1500 tutorial walks you through the complete setup process before performing any ground-fault testing in photovoltaic (PV) systems. Learn how to safely connect the red, black, and green test leads, isolate DC and AC circuits, and verify grounding connections for accurate measurements.
You’ll see how to handle functional grounding links, remove false signal paths, and confirm open-circuit voltage readings that indicate a healthy array. Make sure to follow all PPE requirements and step-by-step safety checks to stay safe.
By mastering this setup workflow, you’ll ensure that every subsequent analysis or fault-trace is accurate, efficient, and compliant with best practices in PV diagnostics.
