The PatchTool Display-Reader tool is designed to make unconstrained emission measurements on any display, even one not connected to the computer on which the program is running. This tool can be used with all PatchTool supported instruments. A timer can be used to take measurements at fixed time intervals. All Standard Observers are available for the i1Pro and i1Pro 2. Only the “2 deg.” Observer is available for colorimeters. The “2F deg.” and “10F deg.” Observers are CIE 170 Standard Observers. When a CIE 170 Standard Observer is selected, you can also export the MacLeod- Boynton Chromaticity Coordinates by selecting the “xyY” data type in the export dialog. You will get the MacLeod- Boynton l MB and s MB coordinates in addition to xyY computed for the selected Observer. Support of CIE 170 cone fundamentals colorimetry (CIE 2006 and CIE 2015) in PatchTool is described in Appendix H of the PatchTool Help manual. Export ABSOLUTE measurements in a RAW file that can be opened in a spreadsheet. Export PROCESSED data in a CGATS compatible file which can be opened in most programs that support this format; this file can also be compared to other colors lists within PatchTool. The CGATS file options dialog which opens after Display- Reader measurements is shown on the next screenshot (Display-Reader CGATS dialog).
