8.2.2 Wavelength Certification, Reflectance
Wavelength Certification is used to confirm the peak positions of the instrument to a defined,
external wavelength standard.
Click on Diagnostics,

Run Wavelength
Certification.
The Number of Samples should be 10, as
shown. The wavelength standard for
reflectance is the “SRM-1920 plus talc”, which
refers to the WSR1xxxx standard. This is the
same cell used for Instrument Calibration.
Click “OK” when ready.
Vision briefly requests that the user place the ceramic reference into position. This is automatic with
the MasterLab Analyzer; no response is required.
When the reference scan is finished, insert the
wavelength standard as directed.
Always place the standard into the instrument in the
same orientation, with the label parallel to the long
axis of the tray.
Click “OK” when ready.
After the test is complete, a spectrum of the standard is shown in the upper right quadrant of the
screen. A tabular report is shown in the lower right quadrant, giving each peak, its nominal position
and its measured position. A typical screen is shown:
