The Hypatia 309 High Current Sourcing Milliohms Meter provides efficient and accurate stress based testing of safety ground systems to insure that they meet certain performance standards of safety certification agencies such as UL, ETL, TUV, CSA, VDE, BABT and others. It utilizes probes with built-in remote sensing or, for multi-point testing or the highest precision measurements, auxiliary Kelvin sense probes. In addition to ground impedance measurements, it can provide and accurately monitor the high currents necessary to test ground system endurance as is required for ground guards on etched circuit boards or in power transformers or other components.
