The process for defining an ellipse or square is very similar to defining a rectangle or square. Essentially, a box
or rectangle is defined, and the PR-655 / PR-670 creates an ellipse or circle inside the box.
Note: To define a circle, the Width and Height values must be identical. For a horizontal ellipse, the
Width value must be larger than the Height value, and for a Vertical ellipse, the Height value must
be larger than the Width value.
1. Touch the field adjacent to CIE Pass / Fail so that it reads Enabled.
2. Touch the
▼▲
icons in the Shape field until Ellipse 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.
