Enter the fiducial mark coordinates. If "2 Points" is selected for the correction method, enter coordinates
for X1, Y1, X2, and Y2. If "3 Points" is selected for the correction method, enter coordinates for X1, Y1, X2,
Y2, X3, and Y3.

the fiducial mark on the board image, click the center of the fiducial mark in the field-of-view image
in the lower left of the screen. After setting the mark parameters, press the [Teach] button when the
test result is "OK". The recognized center coordinates are entered.
Mark
Enter the mark No. This number corresponds to the number in the mark data list.
If "2 Points" is selected for the correction method, enter a number for Mark 1 and Mark 2.
If "3 Points" is selected, enter a number for Mark 1, Mark 2, and Mark 3.

Refer to section 2.4.1, "Basic parameters", on the previous page, and set the following parameters.
Basic parameter settings
[Light List] button
[Measure] button
24215-P6-00
A. Algorithm Type
Set to "Form".
H. Brightness Gain, I. Brightness Offset
Set so that the marks on the board are clearly visible.
M. Shape Type
Select from the drop-down list based on the mark being used.
N. Mark Size (mm)
Enter the mark outline dimensions. (If the outline dimensions are unknown, this procedure is dealt with later at Steps 9
and 10, and therefore there is no need to enter dimensions here.)
R. Circularity
Enter the mark circularity. (If the circularity is unknown, this procedure is dealt with later at Steps 9 and 10, and therefore
there is no need to enter a value here.)
T. Tolerance (%)
Set to 20%.
7
Press the [Light List] button and select a clear image.
By pressing the [Light List] button, a list of images appears. Select an image in which the mark appears
clearly from the image list, and press the [Set] button. When setting is complete, the display returns to
the "Fiducial" screen, and the "D. Light Type" is set.
TIP
If unable to see the fiducial mark clearly with the available lighting in the "Image List", "CUSTOM" lighting can be
selected. For details on the setting method, see 2.4.2, "Setting fiducial mark CUSTOM lighting", in the next section.
