3.2.4. Functional Check
1. After the analyzer’s components has warmed up for at least 30 minutes, verify that the
software properly supports any hardware options that were installed.
2. Check to make sure that the analyzer is functioning within allowable operating parameters.
Appendix C includes 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 performance
problems with your analyzer (Section 11.1.2). The enclosed Final Test and Validation Data
sheet (part number 04307) lists these values before the instrument left the factory.
To view the current values of these parameters press the following key sequence on the
analyzer’s front panel. Remember until the unit has completed its warm up these parameters
may not have stabilized.
