RI Control Unit (Purpose Unknown)

Circa Mid 1960's to Early1980's (ESTIMATED)

An unidentified piece of custom or highly specialized electronic control equipment, possibly a piece of scientific test equipment. Its exact function and manufacturer unknown. Can be equipment rack or console mounted.

Possible Use Cases:

The unit was designed for precise, manual operation and monitoring of external equipment. The features suggest a focus on measuring or supplying electrical signals within a specific range:

• Circuit Monitor: A prominent analog meter to visually display voltage, current, or resistance levels with a range from 0 to 8 units, likely with external scaling.

• Range Selector: A dial with settings from 2 to 128 (likely proportional or logarithmic values) suggests the ability to switch between different measurement scales or output levels.

• Polarity Switch: Indicates it handles DC signals and can reverse the flow.

• Power and Zero Controls: Standard controls for turning the unit on and calibrating the meter.

• Recorder Output: A port labeled "RECORDER" indicates the unit could interface with a chart recorder to log measurements over time.

This configuration is typical for devices such as:

• High-voltage power supplies or controllers for scientific instruments like ion pumps or electron microscopes.

• Specialized test gear for specific electrical engineering experiments.

NOTE: Cosmetically similar to a Duo Control Unit, which is available separately.
