functions of the analyzer. See Appendix A-4 for a complete list of the parameters available for review
under this menu.

Any changes of signal I/O settings will remain in effect only until the signal I/O
menu is exited. Exceptions are the ozone generator override and the flow sensor
calibration, which remain as entered when exiting.
