Press the TRG/BRT key, and the result of measuring (evaluating) and image (search) area will be displayed.
(8) Mesuring the position
*1 The final evaluation result will be displayed as "OK" in the upper left corner of the screen when all of the
items have been evaluated acceptable.
If there is a single unacceptable item, "NG" will be displayed.
*2 "M0 +09620" means that the degree of match (percentage of pixels that match) between pixels in the
stored image and the measured image is 96.20%.
[The acceptance and rejection criteria based on the degree of match]
In order to evaluate acceptability based on the degree of match, first an image of a good specimen is
stored for reference. Then, an image of defective specimen is compared for degree of match. Finally an
image of another good specimen is compared. These comparisons establish the degree of match to be
used for setting the limits used for working comparisons.
For example, the degree of match for a non-defective object is 90% or more and that for a defective
object is 70% or less, then the threshold value for degree of match can be set to approx. 85%. This
allows the evaluation acceptability to be made.
*3 Although the specified data is temporarily stored in RAM memory, it is not stored in the flash memory.
So, you must save the data manually using the save operation. If you do not save the data in the flash
memory, it will be deleted when the IV-S30 controller is turned OFF. - See page 7-26.
