The design and application of a data logging system to monitor discrete electronic components

A Data Logger has been designed and developed by the author. The Data Logger is used to take measurements on electronic components. The Data Logger is outlined. It is described in terms of the hardware from which it was built. It is also described in terms of the software through which it is controlled using an Apple microcomputer. An experiment on multi-layer ceramic capacitors is detailed. A further experiment on optocouplers is outlined. Both experiments make full use of the Data Logger. In concluding, the Data Logger is found to work best with two and three terminal components. Some changes are discussed, enabling the Data Logger to be compatible with the IBM PC format.
