Information

The Type 716-C Capacitance Bridge is a Schering bridge which is direct reading in capacitance over the frequency range from 30 c to 300 kc and in dissipation factor at four specific frequencies, 100 c, 1 kc, 10 kc, 100 kc. The resistance balance is made by means of a variable capacitor connected across one of the ratio arms, as shown in Figure 1. Hence its reading in dissipation factor is proportional to the ratio of the applied frequency to the frequency for which the RANGE SELECTOR switch is set. The bridge may also be used for all types of substitution measurements by the addition of a fixed or variable balancing capacitor. The direct-reading scales greatly simplify the necessary calculations for capacitance and dissipation factor.
