Attached is a spreadsheet with DTP-94 and S2 Sensor Matrices in Excel to add to Zoyd's. I used an i1 Pro to calibrate a Panasonic TH-50PHD8UK, and then used that CHC file as a reference to correct subsequent S2 and DTP94 measures in LCD and CRT modes for each. All the CHC files for each run are included in the zip file with the Adjust XYZ Coordinates option on.
The accuracy of the probes compared to the i1 Pro from Best to worst:
DTP94 CRT Mode - This tracked the i1 Pro very closely - Delta E between DTP94 and i1 Pro reference from 2 to 3.7
DTP94 LCD Mode - Delta E jumped to to about 6.3 average
S2 LCD Mode - Also Delta E 6.3, gray scale tracked the DTP94 almost exactly!, but Y is high
S2 CRT Mode - Delta E 15, this was way off, surprising since it differs from Zoyd's results. I measured 3 times just to be sure!
The S2 CRT results were most surprising. I would have concluded that my S2 was faulty, but since S2 LCD Mode gray scale tracked the DTP94 LCD Mode with a Delta E less than 1, it must be functioning correctly. I will check it again when I have more time.
EDIT: The more I look at this, the more I think I need to retest the S2. The results are just too strange.
EDIT#2: I have confirmed that my S2 is inaccurate - see post http://www.avsforum.com/avs-vb/showt...&#post10476965
The DTP94 numbers are still good.
