The General Radio 716-P4 Guard Circuit was introduced in Catalog N (1954) and remained available through Catalog S (1965).
The Type 716-P4 is an accessory to the 716-C capacitance bridge. Its designed for measurements were the unknown is located some distance or in a test chamber used to simulate a range environmental factors. By the use of 716-P4 it converts the 716-C into a three terminal bridge using double insulated coaxial cable and separate ground to the unknown. The 716-P4 can then balance out the effects of the leads to the unknown.
Specifications
- Capacitance Range: Designed primarily for use with the xl multiplier ranges of the Type 716-C Capacitance Bridge.
- Frequency Range: Corresponds to that of Type 716-C Capacitance Bridge.
- Guard Balance Capacitor: Any value of capacitance between the guard point and the high measuring terminal up to 1000 pF can be balanced out.
