• Concentration : Current measured analyte concentration (ppmv).
•
Wet Temp : Current temperature of the gas sample (degrees C)
when normal sample gas is flowing.
•
Wet Pressure : Current pressure of the gas sample (mb) when
normal sample gas is flowing.
•
Dry Temp : Current temperature (0.0 for non-differential units) of
the gas sample (degrees C) when scrubbed sample gas is flowing.
•
Dry Pressure : Current pressure (0.0 for non-differential units) of
the gas sample (mb) when scrubbed sample gas is flowing.
•
Fit Residue : Value ranging from 0 to 1 indicating how well the
measured spectrum fits the reference spectrum, where 1 represents
a perfect match.
• Fit Ratio : Ratio of the measured spectrum versus the Reference 1
spectrum.
• Dry DC : Signal level (laser intensity in counts, 0.0 for non-
differential units) at the high end of the current ramp during the dry
cycle.
•
Wet DC : Signal level (laser intensity in counts) at the high end of the
current ramp during the wet cycle.
•
Peak Index : Peak index of the measured spectrum.
• Ref Index : Peak index used for reference.
•
Index Difference : Difference between measured and reference
peak indices, where a value other than 0 indicates Peak Tracking is
functioning.
• Val Flg : Indicates current stream being measured (0 = Process,
1 = Val 1, 2 = Val 2).
• Process Path Flg : Calculation path (reference spectra) used for the
concentration calculation (0 = Process Reference Spectra,
1 = Validation Reference Spectra).
•
Current Midpoint : Current midpoint that the analyzer is using,
including any peak tracking adjustments.
•
Fit Ratio 2 : Ratio of the measured spectrum versus the Reference 2
spectrum, where a value of 0 indicates that the Reference 2 spectrum
was not used in the calculation of concentration.
• Fit Ratio 3 : Ratio of the measured spectrum versus the Reference 3
spectrum, where a value of 0 indicates that the Reference 3 spectrum
was not used in the calculation of concentration.
•
Fit Ratio 4 : Ratio of the measured spectrum versus the Reference 4
spectrum, where a value of 0 indicates that the Reference 4 spectrum
was not used in the calculation of concentration.
• Fit Ratio 5 : Ratio of the measured spectrum versus the Reference 5
spectrum, where a value of 0 indicates that the Reference 5 spectrum
was not used in the calculation of concentration.
