The ESI MODEL 707B CAPACITANCE BRIDGE is designed to measure two-terminal or three-terminal capacitors in the range from 0 to 1.2 microfarads with a resolution of 0, 0001 picofarad on the lowest range. The use of a ratio transformer circuit and a hermetically sealed standard capacitor having a very low temperature coefficient of capacitance and exceptional stability assures a minimum effect from changes in room temperature, voltage, and frequency. Accuracy of the measured capacitance is referred to this one standard which can be periodically checked and adjusted to agree with a certified reference standard capacitor . The unknown capacitor is measured in terms of the capacitance and dissipation factor of its equivalent series circuit. Capacitance is presented as an in-line reading including the decimal point and measurement unit. A deviation dial indicates the percent difference between the value of the unknown capacitor and the capacitance dial setting.
