3.5.4. Functional Check
After the analyzer’s components have warmed up for at least 30 minutes, verify that the
software properly supports any hardware options that were installed.
Check to make sure that the analyzer is functioning within allowable operating parameters.
Appendix A and C include a list of test functions viewable from the analyzer’s front panel as
well as their expected values. These functions are also useful tools for diagnosing perform-
ance problems with your analyzer (Chapter 11). The enclosed Final Test and Validation Data
Sheet (part number 04490) lists these values before the instrument left the factory. To
view the current values of these test functions press the keys:
