The detector takes a holmium oxide scan, performs iterative calculations while applying
the rise time and bandwidth filters, and then displays a new message box (see
Figure 67. Calibration message prompting you to return the filter wheel to position 1
7. Move the filter wheel back to position 1, and then click OK to close the message box and
view the results.
8. In the Wavelength File area, check the delta values (see
a. If the delta values are not within the range of ±1 nm, repeat the wavelength
calibration procedure for verification.
b. If, after applying a new calibration, the delta values are still not within the range of
±1 nm, call your Thermo Fisher Scientific service representative for assistance.
