[Procedure]
Place the calibration grid ((1) on the upper-right figure) in the camera FOV.
Place the calibration grid so that the grid pattern covers the entire camera FOV. As long as about 4 x 4 circles, including the four large circles around the center, are in the FOV, circles in the periphery can be outside the FOV.
On the calibration grid, large circles are arranged side by side in an L shape.
Three large circles are placed in line from the corner point of the L shape in the X-axis direction while two large circles in the Y-axis direction.
Do not move the calibration grid until the camera calibration completes in the next step.

TP
Select the tool frame to which the TCP for the touch-up pointer is set. In this tutorial, Tool Frame 2 is used.

TP
In the user frame setting screen, and set the position of the calibration grid to a user frame by four-point teaching. In this tutorial, it is set to User Frame 2 for an illustration purpose.

TP
By following the middle-right figure of the calibration grid, touch-up each of the frame origin ((2) on the middle-right figure), X-axis start point ((3) on the middle-right figure), X-axis direction point ((4) on the middle-right figure), and Y-axis direction point ((5) on the middle-right figure) to record their positions.

PC
In the navigation area, press '3 Cal. Grid Location'. (Refer to the lower-right figure)

PC
For 'Repère de la grille de calibration', select the user frame to which the position of the calibration grid is recorded. In this tutorial, select User Frame 2.

PC
Press the 'Définir' button of 'État position grille de calibration'.
Additional
On the calibration grid, large circles are arranged side by side in an L shape.
Three large circles are placed in line from the corner point of the L shape in the X-axis direction while two large circles in the Y-axis direction.
