General Radio 1615A

The 1615A Capacitance Bridge is an accurate, high-precision bridge for the measurement and intercomparison of standard capacitors, circuit component capacitors, or dielectric materials. Capacitance range is 10E-17 F to 1.11 ?F in six ranges, direct reading. Conductance range is 10E-06 ?mhos to 100 ?mhos (two positive ranges, two negative ranges). Conductance range varies with capacitance range. Frequency is approximately 50Hz to 10kHz. Dissipation factor at 1 kHz is 0.000001:1.
