(Example for adjustment)
An example of adjustment is shown below, using a white object on a black background. When the
dotted line in the window is converted to a binary image, if the lower limit is set higher, the black part
in the binary image will become larger. If the lower limit is set lower, the white part will become larger.
Increase and decrease the lower limit value, find the value at which the white part in the binary image
starts growing and the value at which the black part starts growing. Then set the lower limit at the
value halfway between these points. This will ensure reliable operation.

Window
The IV-S30 captures images using CCDs, which are the light sensitive elements in the camera. The
IV-S30 may capture more than one target image to be measured for image processing, and it may
capture images not required for measurement. In these cases, a window is used to pick out just the
desired target for measurement. The area inside the window will contain the object to be measured
and the areas outside the window will be ignored.

Wizard
The "Wizard" is a program that helps users make settings for measurement operations easily and
without making mistakes. The controller asks you a series of questions at each step and you simply
answer these to complete the settings.
The wizard is convenient for making settings when beginners and inexperienced operators are
operating the machine. However, operators who are familiar with the operation may save a lot of
time by using other setting methods.
