7. Select the Baseline button from the Scan dialog. Follow the on-screen prompts to

perform a 100%T baseline scan and a 0%T baseline scan.

Hot Tip

When performing reflectance measurements, remove the PTFE reference disk from

the sample port and allow the light to be trapped by the magnetic port covers.

8. Once the baseline correction is complete, the Ordinate status display in the top left

corner of the dialog will show ’Zero baseline’ in red text.

9. Clamp the sample over the sample port. The sample should be homogeneous,

substantially flat, and large enough to completely cover the image.

10. Press the Start button. The Save As dialog will appear, allowing the method to be

saved as either a data file or a batch file. If the file is saved as a batch file, all of the

method parameters will be stored with the scan.
