  • Electrical Leakage Testing - CS Medical

    Electrical leakage testing can improve your ability to identify minor probe damage so as to obtain repair before the probe: leaks electricity in a dangerous amount, is damaged beyond repair, has reduced image quality or has corrosion of the internal components. How does testing leakage current affect patient and user safety?
