Error Model Registration (ECM Search)
Even for an image pattern with similar feature sections (for example "P" and "R"), if the model is
registered as an error model, the correlation value is lower and measurement mistakes can be
prevented.Only one error model can be registered.
1.
In the Item Tab area, tap [Error model].
2
2.
This displays the error model image.
Register the error model with the same procedure as for model registration.
Important
Upon re-registering a model, error models are deleted.Register error models when re-registering a model.

Region Setting (ECM Search)
Use a rectangle to specify the area where the model is searched.
Instead of measuring the entire input image, narrowing the measurement area shortens the processing
time.
1.
In the Item Tab area, tap [Region setting].
2.
Tap [Edit].
The figure setting area is displayed.
3.
Specify the area in which to search for the model.
The rectangle covering the entire screen is set. Adjust the size and position of the rectangle.
4.
Tap [OK].
The area to measure is registered.
Detection Point (ECM Search)
Specify a position in the model that should be used as the detection coordinates during
measurement.Usually, the central position of the set model is registered as the detection point.This
function is used to change to any desired position.
Note
After changing the detection coordinates to another position, re-registering the model will change it back to the
●
central coordinates of the model.
1.
In the Item Tab area, tap [Detection point].
In the Image Display area, the current detection point is displayed with a crosshair cursor.
