ABSTRACT:
A circuit for determining the fire no-fire characteristics of electroexplve devices involves the application of an incrementally adjustable current level automatically to successive electroexplosive devices. The initial predetermined current level is applied to the first electroexplosive device under test. The current level applied to the next and succeeding electroexplosive devices is increased or decreased automatically by a predetermined amount, depending on whether the previous unit functioned or not. This method results in a mean firing current level being obtained with less chance for error and less operator involvement than required by presently established procedures.
