Project fist: Fault isolation by semiautomatic techniques: Part I — Basic concept and techniques

FIST has been developed for the maintenance of modularized, noncomputer, electronic equipment. Tests are dynamic, meaningful, rapid, and can be performed by an unskilled technician. System flexibility and concepts may well revolutionize maintenance methods for both military and industrial equipment The method of fault isolation by semiautomatic techniques developed at the National Bureau of Standards, to which the acronym FIST has been applied, is a diagnostic tool for rapidly isolating faults in modularized, noncomputer-type electronic equipment without removing the modules from the prime equipment. The method is simple and flexible and is orders of magnitude faster than trouble shooting with manual test equipment.
