Here's a detailed method for doing the profile.
1. Set up HCFR for the Pro meter and do a normal sensor black level calibration (Measures/Sensor/Calibrate...)
2. Run the primary colors and the white windows reading the data with HCFR set up for the Pro meter. Save the run as something like "pro meter calibration.chc"
3. Set up HCFR for the LT (same as the D2) meter and do a normal sensor black level calibration (Measures/Sensor/Calibrate...)
4. Perform a new run for LT -- this time for the primary colors and the white windows reading the data with HCFR set up for the LT meter. Save the run as something like "LT meter calibration.chc"
5. Display the Pro results on your computer and check the "Reference measure" box in the upper right hand corner.
6. Display the LT results and click Advanced/XYZ coordinates adjustment matrix/Compute conversion matrix from reference document.
7. You will be asked if you want to apply a correction to your LT readings, Click yes.
8. Click Advanced/XYZ coordinates adjustment matrix/Manually edit XYZ conversion matrix...
9. The conversion matrix will be shown. Save it with a name like "LT calibration matrix 01-17-2012"
Done. That's it. Your LT color sensor is corrected to be the as close as possible to the Pro.
N.B. Now when you use HCFR with the LT, make sure that the correction matrix is loaded. If not, load it using the same steps as in item 8.
