Rectangle centered on the screen. The lengths of the sides are 70% of the length and width of the screen.
The white object must be within the rectangle and have an area of at least 10% of the screen.

Note
If the camera has a zoom lens with an automatic iris, the iris may hunt 1) during the adjustment. To prevent this, adjust the iris gain knob (indicated as IG, IS, or S) on the lens.
1)Hunting
Repeated brightening and darkening of the image, resulting from repeated response to automatic iris control.
For details, refer to the lens operation manual.
