4.2.2 Wavelength Setting Repeatability
[Summary]
To find the dispersion of the wavelength readings over multiple
measuring repeated on one emission line from the D
2
lamp.
[Procedure]
1. Choose [Edit] - [Condition setting], then, set conditions as
follows:
‹General tab›

Measurement mode Wavelength scan

Apply sample table OFF
‹Instruemnt tab›

Data mode E(R)

Start wavelength (nm) 660

End wavelength (nm) 650

Scan speed (nm/min) 100

Response Fast

Baseline correction System (*1)

Initial waiting time (s) 0

AutoZero before measuring OFF

Light source switching Use D
2
lamp only

Switching wavelength (nm) 340.0 (*2)

Number of measuring times 1

Cell length (mm) 10 (*1)
‹Monitor tab›

Open data processing window
after measurement ON

Open data processing window
after measurement with
spectrum superimposed
OFF

Automatic printing
on measuring end OFF

Display spectrum on the screen
with superimposed OFF
*1: On-choice setting is available. This setting does not
affect measuring.
*2: This item is masked for protection from a setting by an
operator. This setting does not affect measuring.
2. Choose [Edit] - [Sample name/Comment]. Enter, as the
sample name, “Wavelength setting accuracy”; then, enter the
file name.
3. Click the measuring button ( ). (Measurement starts.)
4. On completion of the measurement, open the data file of which
name was entered at the procedure 2.
