Model 9110TH NOx Analyzer Getting Started
Teledyne Analytical Instruments 77
3.4.3. FUNCTIONAL CHECKS
After the analyzer’s components have warmed up for at least 60 minutes, verify that the software
properly supports any hardware options that are installed.
For information on navigating through the analyzer’s software menus, see the menu trees described in
Appendix A.1.
Check to ensure 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 problems with your analyzer.
The enclosed Final Test and Validation Data sheet (P/N 04409) lists these values before the
instrument left the factory.
To view the current values of these parameters press the following button sequence on the analyzer’s
front panel. Remember until the unit has completed its warm up these parameters may not have
stabilized.
3.4.4. INITIAL CALIBRATION
To perform the following calibration you must have sources for zero air and calibration (span) gas
available for input into the inlet/outlet fittings on the back of the analyzer (see Section 3.3.2.1).
