Option 3: Recognition flag
Option 4: Allowable length error (set as a value in units of 1/10 mm).
Values to be set are those between 0 and 255 (0.1 ~ 25.5 mm).
It does not perform check when the value is 0.
(When setting the value larger than 128, please input the value that 256 is
subtracted from the set value.)
The following is the actual example of the setting and the recognition result.

Figure 58
As described above, sometimes “Special 1” mode does not provide stable recognition.
When the leads for securing the connector are located close to the targeted leads, detection
error may occur as shown in Figure 59.
Figure 59
In this case, stable recognition can be performed by including leads used to secure
connectors as the target in the recognition process as shown in
Figure 60.
