To define a Rectangle or square, two sets of values are entered. The first set is the CIE 1931 x, y coordinate of
the upper left hand corner referred to in the Pass / Fail menu as the rectangles are oriented so that the sides are
parallel to boundaries (axes) of the CIE diagram.
1. Touch the field adjacent to CIE Pass / Fail so that it reads Enabled.
2. Touch the
▼▲ icons in the
Shape field until Rectangle appears.
3. Define the Upper Left Corner by:
a.
Touching the ▼▲ icons in the
Edit field until Corner appears.
b. Touch the gray field next to Left to display the data entry field for the Upper Left CIE 1931 x
coordinate.
c. Enter the value (including the decimal point) then touch Back. This value is the absolute
position of the x coordinate in the CIE 1931 diagram.
d. Touch the gray field next to Top to display the data entry field for the Upper Left CIE 1931 y
coordinate.
e. Enter the value (including the decimal point) then touch Back. This value is the absolute
position of the y coordinate in the CIE 1931 diagram.
4. Define the Size by:
a.
Touching the ▼▲ icons in the
Edit field until Size appears.
b. Touch the gray field next to Width to display the data entry field for the Lower Right CIE 1931 x
coordinate.
c. Enter the value (including the decimal point) then touch Back. This value is the distance from
the Top Left x coordinate in Step 3c.
d. Touch the gray field next to Top to display the data entry field for the Lower Right CIE 1931 y
coordinate.
e. Enter the value (including the decimal point) then touch Back. This value is the distance from
the Top Left y coordinate in Step 3e.
Note: To define a square, the Width and Height values must be identical. For a horizontal rectangle, the
Width value must be larger than the Height value, and for a Vertical rectangle, the Height value
must be larger than the Width value.
5. Following the measurement, touch the
< >
icons at the bottom of the result screen to scroll to the CIE
diagram screen. Pass or Fail appears in the lower right hand corner of the screen.
