4-30 | Model 931S / Model 932S UV Analyzers
Pressure Correction Source
Allows you to choose the method by which the analyzer will use for
pressure compensation for each sensor or the UV species being mea-
sured (either
Measurement [dynamic value] or Default [static value]).
Result Unit Conversion factors **
Result – Species (output) name.
Factor – Conversion factor: 1 = PPMV (1 x 10
4
= %)
Unit – User definable unit (PPMV, %, etc.)
Algorithm Setting check boxes
The compensation settings ( Model 932S Analyzers only ; application
dependant) and allows you to choose an output format:
0 – NDR (Neutral Drift) Compensation
1 – Linearization Compensation 1
2 – Linearization Compensation 2
Output Format
Choose a format to output the Algorithm Setting, either
Concentration , Absorbance , or Transmittance
.
If Absorbance or Transmittance is selected the K-Factor must be
set to ‘ 1 ’:
• Model 931S Analyzers :
From the Optical Bench dialog box, enter ‘ 1 ’ in the K Msr field.
• Model 932S Analyzers :
From the Matrix dialog box, enter ‘ 1 ’ in the top-left text field
and each field going diagonally to the lower-right text field.
Then, set all other fields on the Matrix dialog box to “
0 ”.
Also, disable (uncheck) all Algorithm Setting selections on the
Cell/Misc Parameters dialog box.
IMPORTANT
Before changing these settings, record the values and selected options.
These settings must be returned to their original state when changing
