A SYSTEM FOR CHECKING HAZARDOUS ELECTRIC CIRCUITS,
Abstract
The hazardous circuit ohmmeter and continuity measuring device described make possible a safe, simple method for testing bridge-wire circuits and other ordnance control circuits without the danger of inadvertently actuating or firing the devices. The principle used in both the ohmmeter and the continuity meter is the utilization of the energy output of a photocell which even at light saturation is well below the minimum firing currents. Prototype meters have been built and successfully tested for safety and performance. First production run on the ohmmeter version has been initiated for use in the Polaris program. (Author)
