4.8.2.3 Fixed Temperature and Pressure
The calculated concentrations are compensated for both temperature and pressure.
Typically, this temperature and pressure compensation uses the live values from the
analyzer’s cell temperature and pressure measurement sensors. However, there is also
the capability to use static values of temperature and pressure for this compensation. To
use a Fixed Temperature and / or a Fixed Pressure value for compensation of
concentration values, use the F4 / F3 keys to highlight the checkbox of the fixed value to
be used, then press
↵
to place an X in the box.
4.8.2.4 Sample and Zero Sample Rate
The values shown in the Sample Rate and Zero Sample Rate fields determine how
frequently the analyzer updates the displayed concentrations and air demand when the
analyzer is in sampling mode (Sample Rate) and in back purge mode (Zero Sample rate).
The time values entered in these two fields are in units of milliseconds. The default value
for each sampling rate is 500 ms.
4.8.3 Display
The Display sub-panel, shown in Figure 42, allows the user to configure certain parameters
that affect how data is displayed on the analyzer’s local display screen.

4.8.3.1 Analysis 1 and 2 Trend Graph Ranges
The displayed x and y axes for the trend graphs shown on the Analysis 1 and Analysis 2
panels can be configured by the user on this panel using the Analysis 1/2 X Range and
Analysis 1/2 Y Range data entry fields. The Y ranges are concentrations, affecting the
displayed vertical ranges on the Air Demand trend on the Analysis 1 panel and the
Component concentration trends on the
Analysis 2
panel. These scales can be adjusted
if any of the trend lines are found to be commonly going off of the currently displayed
scale. The X ranges are time, affecting the amount of time represented by the displayed
