Wire is run through mercury-filled vessel. Bridge output goes to pair of mixer tubes (6AJ8 is U.S. equivalent) whose plate circuits form d-c vtvm, with milliammeter indicating amount of bridge unbalance. Bridge is formed by connecting mercury vessel, grounded wire, fixed capacitor, and variable capacitor to secondary coil of differential transformer.-Monitor Wire Enamel by Capacitance Bridge, Electronics, 33:44, p 92-97.
