  ► If possible, use the optional CT SB2 switch box for testing multi-ratio CTs. The CT Analyzer then automatically reduces the test voltage in a way that the maximum possible voltage within the measurement setup (i.e., the voltage occurring at the tap combination with the highest ratio) is limited to 200V.
