Safety Standards Measuring Instruments HIOKI 3157 AC QHOUNDiwa H TESTER CE certified low-resistance measurement compliant with major safety standards Protective ground tester indispensable for standard certification The AC GROUNDING HiTESTER 3157-01 is designed to measure whether the metal enclosure of an electrical equipment is connected to the ground terminal at sufficiently low resistance levels. It also can be used to evaluate the grounding conditions of large-scale electrical installations. Measurement is carried out by using a high current according to the specifications of the measurement object, and determining the voltage drop at the measurement point. Reference values are as set out in the various safety standards. The 3157-01 can carry out measurements in accordance with the stipulations of multiple HIOKI company overview, new products, environmental considerations and other information are available on our website.

1 Low-resistance measurements in accordance with all major safety standards Main applications The 3157-01 passes a large AC current through the measurement object and measures the voltage drop according to the AC 4-terminal method, making it possible to measure very low resistance values. ● Protective grounding checks of medical and general electrical equipment ● Ground connection tracing of machine tools and wiring panels ● Safeguard and equal-potential connection checks of medical installations ● High-current behavior evaluation of  connections Major features ■ Compliant with a multitude of...
