Description
Set a lower limit value for the similarity.
The similarity is the level of resemblance of the character that is
read to the font information of the correct string. The more the
read character resembles the font information of the correct string,
the higher the similarity.
Set a lower limit value for the stability. The stability is expressed as
the value that results when the similarity of the second candidate
for the read character is subtracted from the similarity of the first
candidate. The lower the amount of difference in similarities
between candidates, the higher the possibility that a character
reading error will occur. If the 2nd candidate can not be detected,
the stability is output as 100 regardless of the correlation of the 1st
candidate.
The result is "OK" when the stability is higher than the "Stability".
This can be set when "OCR + Count" is selected for the inspection
mode.
Set the judgement condition for the number of characters on the
1st line.
This can be set when "OCR + Count" is selected for the inspection
mode.
Set the judgement condition for the number of characters on the
2nd line.
This can be set when "OCR + Count" is selected for the inspection
mode.
Set the judgement condition for the number of characters on the
3rd line.
This can be set when "OCR + Count" is selected for the inspection
mode.
Set the judgement condition for the number of characters on the
4th line.
This can be set when "OCV" is selected for the inspection mode.
Select the specification method for specifying the character
verification string. Use [Unit] if wanting to use the measurement
results for other processing units in the measurement flow as the
character verification string.
The setting is enabled if [OCV] is specified for the inspection mode
and [Unit] is specified for the OCV condition.
Select the processing unit with the measurement results that are
to be used for the character verification string.
A list of processing items that can be selected for the reference
unit is given below.
• 2DCode
• Barcode
This can be set when "OCV" is selected for the inspection mode.
