Abstract
Certain types of resistive components for the electronics industry are produced by an automatic process at the rate of 1200 components per hour. The resistance of these components must not exceed a specified value. Components which have a resistance greater than this value are defective and have to be scrapped. Some parts of the process deteriorate with the passage of time and cause the resistance of the components being manufactured to increase. When this resistance reaches such a value that defective elements are being produced, then the process is stopped and reset.
