Abstract
Exemplary methods and apparatus for testing an electrically fired item, e.g., a primer-only cartridge or all-up round (AUR) cartridge, in a variety of modes are provided. For example, a test system may provide a method of testing a primer-only cartridge and an apparatus to execute such method. Various parameters associated with operation of the electrically fired item, such as a primer or initiator, may be varied and measured using an embodiment including programmable selection of a pulse duration for firing control signals, a voltage of the firing control signals, and a number of pulses associated with the firing control signals. An inline resistance of the path of the control signals may also be adjusted. Test data including temperature, pressure, voltage, and/or current associated with operation of the electrically fired item may be measured during tests and displayed on a display device.
