Vision requests the “Standard File” for the Certified
Wavelength Standard.
Place the mini-CD into the CD drive, and select the
standard file. Click “Open”.
Vision prompts the user to insert the WSR10xxx
standard into the instrument.
Insert the WSR10Xxx Wavelength Standard Cell when
prompted. Use the tray provided for this purpose.
Insert the standard with the label parallel to the long
axis of the tray.
Click “OK” to continue.
This test takes about 45 seconds.
At the end of the test this dialog box is displayed.
Print confirmation of test results if needed for a log

During Instrument Calibration, 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.
