4.2. SAMPLE MODE
This is the analyzer’s standard operating mode. In this mode the instrument is
analyzing the gas in the sample chamber, calculating O2 concentration and
reporting this information to the user via the front panel display, the analog
outputs and, if set up properly, the RS-232/485/Ethernet ports.
A variety of TEST functions are available for viewing at the front panel
whenever the analyzer is at the MAIN MENU. These functions provide
information about the various functional parameters related to the analyzers
operation and its measurement of gas concentrations. This information is
particularly useful when troubleshooting a performance problem (see Section
11.1.2).
To view these TEST functions, press,
Figure 4-2: Viewing Test Functions
Note A value of “Warnings” displayed for any of the TEST functions indicates an
out-of-range reading or the analyzer’s inability to calculate it.
Note 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.
