ABSTRACT:
An apparatus for simultaneously testing a large plurality of conductive paths on a bare printed circuit board for short circuit and open circuit conditions. The bare printed circuit board has a rear surface which includes a plurality of terminals located at the opposite ends of the conductive paths to be tested and a plurality of terminal-engaging electrical contacts are provided for operatively engaging the terminals on the rear of the printed circuit boards when the two are forced together. A first set of LEDs on a display panel is used to test for shorts and a second set of LEDs is used to test for open circuits, and a single glance at the display will indicate, not only the presence of a short or open circuit condition, but the exact location thereof.
