Observe in the White Spec portion of the window:
1. deg K and duv. These are read only values calculated from xy (or u'v') below. Use the Main window
"Kelvin Calculator" to see the degree Kelvin values for xy or u'v' values.
2. u'v'Y' ( or xyY). These are the target (spec) values for white for this cal file.
3. Y tolernace in %. For the OK / NoPass indicator, this is the amount Y can vary and still be in spec.
4. xy tolerance mode, u'v' tolerance mode. This determines what the native mode of the colorimeter will
be when this cal file is chosen. If xy is chosen, the colorimeter will prefer to show color in xy values when
first opened, and will make QC graphs with axis labeled as x and y. If u'v' is chosen, the colorimeter will
prefer to run in the u'v' mode.
5. u'v' (or xy) tolerance value for OK / NoPass tests.
The white point spec values may be edited by clicking on the Calibration File window "Edit Values"
button. Before making any other changes, choose xy or u'v' spec by clicking on the "Spec Units xy" or
"Spec Units u'v'" radio button. Then also choose the "tolerance xy" or "tolerance u'v'" to match this
choice. The remaining xyY and tolerance values may be edited. Notice that the degK value is non-
editable, and follows the value of xy (u'v') entered. When you have edited the white spec values to your
liking, press the button "Save As" (which appeared in the Calibration File window when edit mode was
entered. A new small window appears:
Choose a new File Number (1-96) and a new File Name (1-16 letters) and Extension (4 letters). The file
name should match the name of a model of display for which it is to be used. The Extension value
should match the name of one of the white point specs for tat monitor (9400 or 6500 would be good
