* About

The Component Tester is based on the project of Markus Frejek [1&2] and the
successor project of Karl-Heinz Kbbeler [3&4]. The Opto Coupler Adapter
provides a simple way to check opto couplers. It supports BJT types in DIL-4
and DIL-6 packages, and also TRIAC types in DIL-6 package.


* Safety Advice

The Adapter doesn't provide any input protection. Don't connect any external
signal! Only plug in one single opto coupler!


* What's in the box?

Following files are in the archive:
- this README
- schematics in PDF format
- schematics and PCB layout for Eagle 7.5.0 or later


* Layout

The layout is optimized for home lab PCB production.
