U3 User's Guide
The complete user's guide for the U3, including documentation for the LabJackUD driver. Covers
hardware versions 1.20, 1.21, and 1.30 (LV/HV).
To make a PDF of the whole manual, click "Export all" towards the upper-right of this page. Doing so
converts these pages to a PDF on-the-fly, using the latest content, and can take 20-30 seconds.
Make sure you have a current browser (we mostly test in Firefox and Chrome) and the current version
of Acrobat Reader. If it is not working for you, rather than a normal click of "Export all" do a right-click
and select "Save link as" or similar. Then wait 20-30 seconds and a dialog box will pop up asking
you where to save the PDF. Then you can open it in the real Acrobat Reader, not embedded in a
browser. If you still have problems, try the "Print all" option instead. In addition, an export is attached
below, but will not always be the latest version.
If you are looking at a PDF or hardcopy, realize that the original is an online document at http://labjack.com/support/u3/users-guide.
Rather than using a PDF, though, we encourage you to use this web-based documentation. Some advantages:
We can quickly change or update content.
The site search includes the user's guide, forum, and all other resources at labjack.com. When you are looking for
something try using the site search.
For support, try going to the applicable user's guide page and post a comment. When appropriate we can then immediately
add/change content on that page to address the question.
One other trick worth mentioning, is to browse the table of contents to the left. Rather than clicking on all the links to browse, you
can click on the small black triangles to expand without reloading the whole page.
