CircuitWerkes Support (PDF manuals and software)

Manuals have a funny way of walking away just when you need 'em, so this way you always have our information available to you. The books are in Adobe Acrobat 3.0 PDF format. If your version of the reader is 2.xx or older, it will not work, so you'll need to download a free copy of the latest Acrobat reader (ver. 7) or you can click here to install it on your Windows 2000 or XP computer. For older Windows systems, Acrobat 5 may be installed.

This page contains links to current production product manuals and software. If you have an older CircuitWerkes product, you can find out-of-production items here .
