6. OPERATING INSTRUCTIONS
To assist in navigating the analyzer’s software, a series of menu trees can be found in
Appendix A of this manual.
NOTE
The flow charts appearing in this section contain typical representations of the
analyzer’s display during the various operations being described. These
representations may differ slightly from the actual display of your instrument.
The ENTR key may disappear if you select a setting that is invalid or out of the
allowable range for that parameter, such as trying to set the 24-hour clock to
25:00:00. Once you adjust the setting to an allowable value, the ENTR key will re-
appear.
6.1. Overview of Operating modes
The M100E software has a variety of operating modes. Most commonly, the analyzer will
be operating in SAMPLE mode, in which a continuous read-out of the gas concentration
is displayed. Calibrations can be performed, and test and warning functions can be
examined.
