Laser Adjust Tab
Use the
Laser Adjust tab to manually adjust the laser’s wavelength to compensate for any
cumulative drift. (Figure 38)
Laser adjustment may be needed for the following reasons:
The laser’s wavelength has drifted beyond the target range of the analyzer.
The analyzer is operated outside the recommended temperature range.
Figure 38 shows a example of the offset between absorption peaks and target lines. For a
2-laser system, both lasers are adjusted separately.
