Revision 5 100 August 2021
The parameters on this page are configured at the factory and in general should not require
changing once the analyzer is in operation. When this page is first opened, it is opened in read-
only mode. In order to make changes on this page, click on Change to Update Mode at the top
right corner of the screen. A LOGIN dialog box like the one shown in Figure 61 will appear. After
entering the correct password (default is 9713) the page will change to Update mode and these
parameters can then be edited.
The parameters displayed on this page are colour-coded as described in Table 28.
Table 28: Factory Parameters Colour Code
Background Colour Type of Parameter
Blue Parameters related to the analyzer’s analog outputs
Grey Parameters related to the analyzer’s spectrometer
Green Parameters related to calculation of analytical results
Most of the parameters that are available for editing on this page can be edited at the analyzer
local display using the keypad, though a few cannot. The available parameters are described
briefly in Table 29.

Explanation
Air Demand Full Scale (-
/+)
Y Config – Outputs
In previous software versions, AO1 was
hardcoded to output Air Demand, and this
parameter was used to set the range of the air
demand output. In current software version, all
AOs can be configured individually, so this
parameter has no real use.
Dark Start Pixel N N/A
Pixel number (out of 2048) where the
spectrometer starts looking at the dark level.
The displayed dark level is an average of the
dark level on all pixels between this pixel and
the first vector pixel.
NOTE: This parameter is unique to each
spectrometer and should ONLY be changed
if the spectrometer is changed.
First Vector Pixel N N/A
Pixel number (out of 2048) on the spectrometer
that is used as the first pixel out of the 530
consecutive pixels that are used for analysis.
NOTE: This parameter is unique to each
spectrometer and should ONLY be changed
if the spectrometer is changed.
H2S, SO2, COS, CS2
SVAP span factor
Y Config – Calculation
Span factors used for each measured
component. The concentration of each
component calculated from the absorbance
spectrum and the calibration matrix are
multiplied by these span factors to produce the
displayed and output concentration value.
Should be close to 1 for each component.
Setting to 0 will make the analyzer unable to
measure that component.
Cell Length Y Config – Calculation
Measurement cell length as measured from
inside of one cell window to the inside of the
other cell window. Should only be changed if
the measurement cell block is replaced with a
block with a longer or shorter measurement cell
length.
