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.
6.2.2. Warning Messages
The most common instrument failures will be reported as a warning on the analyzer’s front panel
and through the COM ports. Section 11.1.1 explains how to use these messages to troubleshoot
problems. Section 3.2.3 shows how to view and clear warning messages.
Table 6-3 lists all warning messages for the current version of software.
