to display the “Custom AOI” window.
With the Custom AOI window displayed, drag the live image on the monitor to designate the
rectangle for the light measurement area AOI. While being dragged, the lines of the rectangle are
displayed in red (dotted lines) and when the AOI is determined, the lines of the rectangle are

Drag inside the AOI rectangle to move the AOI. Drag the corner or the periphery of the AOI
rectangle to change the size of the AOI. Drag the outside of the AOI rectangle to eliminate the
current AOI and designate a new AOI. Coordinates can be designated in the Custom AOI window
(starting point X, starting point Y, width, and height). Click “OK” in the Custom AOI window to
finalize the settings.
