24. Reading the 507 nm emission line
spectrum at the emission side
Scan the emission side grating in the vicinity of 507 nm,
and record the peak of light intensity with the
photosensor at the emission side.
25. Reading the 761 nm emission line
spectrum at the emission side
Scan the emission side grating in the vicinity of 761 nm,
and record the peak of light intensity with the
photosensor at the emission side.
26. Resetting of the grating positions The excitation and emission gratings are returned to
their positions before wavelength calibration started.
27. Judgment of wavelength accuracy It is checked whether the wavelength accuracy is within
±2.0 nm at 254 nm, 507 nm and 761 nm on the
excitation side, and at 254 nm, 507 nm and 761 nm on
the emission side.
If all the values satisfy the check criteria, [CHECK
GOOD] is displayed.
If even one of the values doesn't satisfy the check
criteria, [CHECK NG*] is displayed.
