Many documents on the Controllab Products site are stored in Adobe's Portable
Document Format (PDF). The advantage of PDF as a file format is that it
preserves the form of documents across a wide variety of computer platforms,
printers and electronic distribution methods. You can view, navigate and
print documents stored in PDF using the free Acrobat Reader.
The reader can be used stand alone, or as a web-plugin.
If you haven't got the Acrobat Reader, get yourself a free copy
from the Adobe
internet pages.
