Designed specifically for electrical safety testing of power tools and extension cords, the SafeCheck 5S safety instrument is designed to simplify a comprehensive test routine. Features like semi-automatic testing walk the operator through the test, and provide clear “pass” or “fail” indications. Particularly valuable for applications where tools may incorporate an integral “no volt” operating switch, the SafeCheck 5S performs tests that include Ground Bond, Short Test, Leakage, and Continuity and Polarity of extension and power cords.
