Figure 4-2: Viewing 9110TH/M TEST Functions
Note A value of “XXXX” displayed for any of the TEST functions indicates an
out-of-range reading or the analyzer’s inability to calculate it. All pressure
measurements are represented in terms of absolute pressure. Absolute,
atmospheric pressure is 29.92 in-Hg-A at sea level. It decreases about 1
in-Hg per 300 m gain in altitude. A variety of factors such as air
conditioning and passing storms can cause changes in the absolute
atmospheric pressure.
4.2.2. WARNING MESSAGES
The most common instrument failures will be reported as a warning on the analyzer’s
front panel and through the COM ports. Appendix A provides the recommended action
and explains how to use these messages to troubleshoot problems. 7.1.1 shows how to
view and clear warning messages.
