After importing your data, you need to edit the following fields under "Corrections"

  • Zero error = -0.1308 1042 (Fixed)
  • Sample displacement: For a perfectly mounted sample, the sample height is approximately -0.3201 2550 mm. However, this value you can refine to fit your sample.

These values have been found by using fitting both the measurements of NIST 660a (LaB6) and NIST 1967a (corundum standard) standards simultaneously.

Example: How to refine for a LaB6 sample (coated on Si-wafer). Keep Zero error fixed at "-0.13081042", whilst refine the sample height.
