Following Wavelength Linearization, the user is
asked to select a standard file. This is provided on
the diskette in the Certified Standard box. It may
be manually copied on the computer in the Vision
directory, as shown.
Select this file and click on “Open”.
Vision prompts the user to position the WSR103xx
standard on the probe.
When prompted, position the WSR103xx
Wavelength Standard Cell on the probe as shown.
The label should always be in a consistent position.
In this case, the bottom of the label is parallel with
the holder.
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.
