instrument is fully warmed up would be beneficial.

NIR 0%T correction

This closes the shutter and calibrates the NIR detector for 0 %T errors. If a DRA is

connected a mask must be placed in front of the transmission port (rear instrument beam)

during the calibration process. The software will prompt you for this.

Auto calibrate

Will perform all the calibrations relevant to the instrument and DRA combination being

used. User interaction is required if a DRA is in place.

Wavelength status

This allows the user to view the Wavelength offsets stored in the EEPROM.

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.

3. Set the following parameters:

Cary tab

X mode: Mode Nanometers

X mode: Start 300

X mode: Stop 2000

Y mode: Mode % R

Y mode: Y min -5.00

Y mode: Y max 110.00
