The ED&D GC1000 Automatic Ground Impedance Tester utilizes high current for measuring the grounding circuit impedance of a product. The GC1000 applies a constant AC test current (25A or 30A) and measures the voltage drop across the grounding path being tested. The resulting impedance is displayed with a 0.10 ohms pass/fail trip limit. The test current is provided in the series path from the ground pin of the front panel receptacle, through the grounding path being tested, to the RETURN lead.
