The Desco 19351 Two State Wrist Strap Tester (220V AC) connects to utility ground when plugged in for a quick installation and grounding of both wrist straps and table mats. The entire circuit-- wrist strap, cord, and skin contact-- are all tested for a reliable resistance test. No other ground cords are needed as the unit acts as a common point ground for the work-surface.
