Watch as we walk through the full process, from initial setup to real-world testing of the Handheld DC Resistance Tester. In this video, you'll see how to perform accurate DC resistance measurements on transformer windings, tap changers, and reactors using automatic current selection, built-in battery operation, and safety features like automatic discharge. Ideal for field technicians and maintenance engineers working in transformer commissioning, troubleshooting, and preventive testing.
