Performing a correction to ASTM E903-C-OS/2

If you are using a NIST Standard Reference material (SRM) (e.g. White ceramic tile)

as the reference disk then you should enter the calibrated reflectance values as a

continuum in the Cary system. To do this, create an ASCII file and enter the list of X

and Y data pairs (separated by commas). Save this ASCII file in the '.CSV' format

If you are using the PTFE reference disk supplied with the DRA, then the following

values may be used. These values are approximate only. The PTFE reference plate

has not been calibrated. The reflectance values are representative of the PTFE

reference plates supplied with the DRA(3).

1. Click the Windows Start button, then Programs, then Cary WinUV, and then

Scan.

2. Click the Setup button.
