Abstract

A test tool is described for facilitating testing of a power supply having multiple output voltage levels. Under normal testing conditions the individual output voltage levels would be measured by a customer engineer with a voltmeter. In the specific power supply under consideration a total of 28 voltage levels exist, and manual testing is time consuming and costly. The test tool illustrated in the figures is designed to measure the presence of seven voltage levels at each one of the test plugs by simply plugging in the test tool (Fig. 1). If all the voltages are present, a row of seven light-emitting diodes (LEDs) lights up indicating that there is voltage present (Fig. 2). If any LED does not light, it indicates that a voltage level is not present.
