FSQS-30 manual HV Capacitance Bridge is widely used to measure capacitance and tan delta for cables and other electric products, it adopts theory of current comparer, combining computer data processing, easy to operate, and with high measuring accuracy, multiple digital reading and good linearity. The inner computer can process data automatically, and display capacitance, the test voltage, current through capacitor（Icn）. Through printer, the result can be printed.
