Wavelength Calibration Lost
After exchanging the monochromator assemblies, the calibration factors
should be reset to defaults values (a new FLM board comes with default
values). In this case “Wavelength Calibration Lost” is displayed and the
instrument stays in a Not Ready condition.
Probable Causes
• Reset of monochromator settings after exchange.
• Replacement of FLM board.
Suggested Actions
✔ Perform a wavelength calibration.
