 The {{Title|General Radio 1611-B Capacitance Test Bridge}} was introduced in {{Catalog P}} and remained available through {{Catalog S}}.
-The Type 1611-B self contained capacitance bridge operating at 60 Hz. It can be used at 120 Hz with an external oscillator and filter, the Type [[1214-D]] is recommended. Capacitance measurements at 120 cps are used primarily for the measurement of polarized electrolytic capacitors. A 6E5 "Eye" tube is used as the null indicator along with a detector sensitivity control.  The bridge is suitable for testing of paper, mica, and electrolytic capacitors with 1% accuracy.
