Wavelength Accuracy - Jasco V-530 Hardware/Function Manual

4.4.3 Wavelength Accuracy

Measure the spectra of the D
and read the peak wavelength.
(1) Light only the Deuterium lamp by following items (1) to (3) in Section 4.4.2.
(2) Select [Single Beam] from the [Environment] menu to display the [Single Beam]
screen. (Refer to Section 9-5 of the Operations manual.)
(3) Display the [Parameter] screen and set the following parameters.
<<Parameters for spectrum with an emission line 656.1 nm>>

All other parameter settings are the same as shown above.
(4) Measure the single beam spectrum with the sample chamber empty to obtain the
emission line spectra of the D
and Fig. 4.6.
(5) Wavelength accuracy is normal if the measurement results are within the following
criteria.
<V-530 criteria>
<V-550/560/570 criteria> Within 656.1 0.3 nm
(6) Display the [Others] screen again and return to the original settings (WI & D2).
