Abstract
A ramp current method of sensitivity testing allows a dynamic record to be btained of the current, voltage, and energy, as well as resistance and instantaneous power necessary to fire electroexplosive devices. This method is most valuable in that useful information is gained from each firing and thus only minimum sampling is utilized. The ramp method also allows a defective item to be detected rather than recorded as a less sensitive device and therefore as an erroneous data point, contributing to more accurate firing data.
