Application Notes
The tube is designed to convert electrical information into optical signals. The figures become visible at the same spot, making possible 'in-line' read-out. Used in digital voltmeters, cash registers, and calculating machines. Can be controlled by mechanical switches, transistors, or cold-cathode trigger tubes.
