The report describes the development of an automatic capacitance measurement system. The system was specifically designed to be compatible with a capacitive strain gage working in ambient temperatures up to 1500F. The progression of the development yielded a system capable of measuring three terminal capacitors at a distance of up to 150 feet. The system measures capacitances from 10 to 30 pf and automatically balances the loss component. Four frequencies of operation are selectable for system operation. The outputs of the system are a D.C. voltage of 50 mvpf and a digital indication of capacitance.
