When Good Capacitors Go Bad - Revisited. Capacitor problems are a leading cause of equipment performance degradation and failure. Doug Jones of Midwest Devices will offer a tutorial on capacitor troubleshooting, with particular emphasis on effective series resistance (ESR). Jones has a new demonstration showing how you cannot rely on capacitance reading meters.
Jones is the owner of Independence-based Midwest Devices and is the designer of the Capacitor Wizard, an in-circuit ESR meter. He has also designed and built test equipment for the cable television industry.
Godfather's offers a lunch buffet. When you arrive go to the counter, pay for your lunch, get your food, and then meet us in the front banquet room for lunch and the meeting.
