Digitized two-dial potentiometer
F. E. Hoare, D.E. Moody · Journal of Scientific Instruments · 1962
A commercially available 0.0001 to 1.02 v potentiometer with three range switch positions has been digitized. By periodic actuation from an external source the readings, including the position of the range switch, are automatically recorded on punched tape. Although designed for a particular application it may be used economically where a number of potentiometer readings have to be taken.
