(5) The wavelength repeatability is normal if it is within the following criterion.
Criterion: Within ±0.1 nm of the average value of the peaks of the spectrum with
an emission line at 656.1 nm
(6) Display the [Environment] menu again and return to the original settings (i.e. check
the [Deuterium] and [Halogen] boxes).

4.3.3 Wavelength Accuracy

To check wavelength accuracy, measure the spectra of the D
line at 656.1 nm and 486.0 nm.
(1) Light only the Deuterium lamp (see item (1) in Section 4.3.2).
(2) Start [Spectrum Measurement] from the [Spectra Manager] window and set the
following parameters.
