check (Fig. 5-7). For display method, follow the procedure
starting from section 5.1.. Using the [▲]/[▼] key, move
the cursor to Repeatability of WL, and then select [1] Yes.
Wavelength repeatability will be checked. If check is not
desired actually, select [2] No.

After the check of wavelength repeatability, the screen after
this check is displayed as shown in Fig. 5-9.
Measurement result is indicated on the wavelength
repeatability line followed by OK when the judgment
standard is met or NG if not met. If NG is indicated, check
the wavelength repeatability again in the correct procedure.
If NG recurs, refer to section 6.8 .
