If wavelength calibration verification fails and there is an error message stating that peak
wavelengths are outside limits, then wavelength and laser frequency calibrations should be
performed. When these calibrations have finished, repeat the wavelength verification to
ensure that the instrument has been brought back within specification.
If the wavelength calibration verification fails because the spectral intensity is low, then this
may also be due to the calibration sample holder not being placed in the sample accessory,
or that it is not correctly positioned, optimally focused or because the laser key is not
switched on. Then repeat the wavelength calibration verification to ensure that instrument
has been brought back within specification. If the instrument fails the wavelength calibration
verification again, please contact PerkinElmer.
