The General Radio 1611-B Capacitance Test Bridge was introduced in Catalog P (1959) and remained available through Catalog S (1965).
It is a self-contained capacitance bridge suitable for testing of paper, mica, and electrolytic capacitors with 1% accuracy.
A 6E5 tube (the first Magic Eye) is used as the null indicator along with a detector sensitivity control.
The 1611-B is operating at 60 Hz, or 120 Hz with an external oscillator and filter (Type 1214-D was recommended). Capacitance measurements at 120 Hz are used primarily for the measurement of polarized electrolytic capacitors. The 1611-BQ1 variant was available for 50 Hz line frequency.
Specifications
- Capacitance Range: 0 to 11,000 μF in eight ranges
- Test-Voltage Frequency: 60 Hz with internal supply and filter; 120 Hz with external supply on four higher multipliers
- Capacitance Accuracy: ±(1% + l pF) over the entire range
- Dissipation-Factor Range: 0 to 60% at 60 Hz (x f/60 at other frequencies)
- Dissipation-Factor Accuracy: ±(2% of dial reading + 0.05% x f/60 dissipation factor)
