Next Wavelength Linearization is performed in two
sections, each of which takes about 25 seconds.

Following Wavelength Linearization, the user is asked
to select a standard file. This is provided on the diskette
or CD in the standard box.

Select this file and click on “Open”.

Vision prompts the user to insert the wavelength
standard that is associated with the chosen standards
file into the instrument.

Insert the indicated wavelength standard when
prompted.

Click “OK” to continue.

This test takes about 45 seconds.

The wavelength response for each defined peak is adjusted, to assure precise wavelength registration
between instruments. At the same time, bandwidth (bandpass) is measured, and is iteratively
adjusted to an optimum value for the peaks measured. This is performed to assure good agreement
from instrument to instrument, should multiple instruments be used for analysis of similar products.

At the end of the test this dialog box is
displayed.

Click “OK” to exit Instrument Calibration.
