Wavelength Repeatability - Jasco V-530 Hardware/Function Manual

Note: This data is used for correcting the baseline spectrum (0 Abs line) to be
measured in (4) below.
(4) Measure baseline spectrum (0 Abs line) as follows. Click the <Start> button to
measure the baseline spectrum (0 Abs line) using the above parameters with the
sample chamber empty. A measurement example is shown in Fig 4.1.
(5) The baseline flatness is normal if the measurement result is within the following
criterion.
<V-530 criterion>
<V-550/560/570
criterion>

4.3.2 Wavelength Repeatability

To check wavelength repeatability, measure the spectrum of the Deuterium (D
with an emission line at 656.1 nm three times repeatedly.
(1) Light the D lamp as follows.

a) Start [Environment] from the [Spectra Manager] window. The [Environment]
dialog box appears.
b) Select [Hardware Setting] and then click the <Execute...> button. The following
dialog box appears.
Within ±0.001 Abs (1000 ~ 200 nm)
Within ±0.001 Abs (850 ~ 200 nm)
