Megger Insulation Test Results

The document summarizes the results of an insulation resistance test performed on July 8, 2020 at the Karl Storz Endoskope facility. Insulation resistance measurements were taken of 16 circuits serving lighting outlets, air conditioning units, and convenience outlets. The main feeder wire showed a resistance of 500Ω across all phases. Most branch circuits measured between 4-5.5Ω except circuits 7 and 12 which showed lower resistances of 2.32Ω and 4.05Ω respectively. The tester and multi-meter used were verified as properly calibrated and in working order.
