Defining the monitoring area
The monitoring area is defined with the modes of operation
Single Block or Block Scan. The TNC will prompt you to define a
monitoring area. The TNC will display this prompt on the screen
after you have started the cycle for the first time in the modes of
operation Single Block or Block Scan.
A monitoring area consists of one or more windows that you
draw with your mouse. The TNC will only scan these areas of
the image. Errors outside of the monitoring area will not be
detected. The monitoring area is not linked to images but only
with the appropriate monitoring file QS600. A monitoring area
always applies to all images of a monitoring file. A change to the
monitoring area affects all images.
Monitoring areas may overlap.
Definition of the monitoring area:
1 Click with the mouse on the image and draw a new area
2 If you would like to define more than one window, press the
DRAW AREA soft key, and repeat this process at the appropriate
location
After you have defined the monitoring area you press the
following soft key, for example:
Save current image and return to previous
screen.
Message displayed: Monitoring point is
configured: Select the soft key.
The status display at the top right of the image will
display information about the minimum number
of reference images, about the current number of
reference images and the current number of error
images.
