Hardware problems can have several causes. The first step to identifying a
problem is to review the installation instructions in this manual to verify that you
have properly installed the instrument. The second step is to determine if the
problem is in the mainframe or the measurement set’s modules.
If you are certain that you have installed the instrument correctly, run the
extended diagnostics (located under the tools menu) to identify any problems
with the individual modules.
