Table 21: Analyzer Warnings
Warning Explanation
Low Cabinet
Temperature
Control cabinet internal temperature is below low cabinet temperature
setpoint
High Cabinet
Temperature Control cabinet internal temperature is above high cabinet temperature
setpoint
Low Reference
Peak
Spectrometer signal peak height when analyzer is in back purge mode
<24000 A/D counts
High Integration
Period
Integration period required to obtain an in-range spectrometer signal
when analyzer is in back purge mode > 500 milliseconds.
High Absorbance Measured absorbance >2.0AU when analyzer is in sampling mode.
High Sulfur
Vapour
Measured sulfur vapour content exceeds high sulfur vapour
concentration warning setpoint
Some of these warnings may clear by themselves but others will not be able to be cleared
without performing maintenance on the analyzer. Refer to section 7.2 for more detail on how
to troubleshoot active warnings.
5.2.4 Spectrum Page
The Spectrum page shown in Figure 50 shows identical information to the Spectrum panel
on the analyzer’s local display.
Figure 50: Spectrum Page
The Spectrum Curve, or transmission spectrum, displayed on this page shows the intensity
of light measured at each of the 2048 pixels of the spectrometer. The exact X (pixel number)
and Y (A/D counts) coordinates of each data point on the curve can be determined by placing
the mouse cursor over the data point of interest. The Y-axis scale can be adjusted by clicking
on the
Change Spectrum Curve Display Y Axis button. The Y-Axis Maximum Value
dialog box shown in Figure 51 will then appear.
