Setting the Measurement Parameters

When you perform teaching, the measurement parameters are set automatically. If the automatic settings are
incorrect for any reason, e.g., the read result was incorrect, set the measurement parameters manually and
then perform teaching.

Setting
Sets whether to verify the read character string against a character string that
is registered in the master data.
To verify the read character string against the master data, select the character
string to use for verification.
Registers a character string in the master data.
Sets the character string in which to automatically register the read result for
teaching from an external device.

Description
Sets the color of the characters to detect.
Sets the type of printing of the characters to detect.
Adjusts the vertical dot interval of the characters to detect. This parame-
ter is enabled only when [Printing type] is set to [Dot character].
Adjusts the horizontal dot interval of the characters to detect. This
parameter is enabled only when [Printing type] is set to [Dot character].
Sets the thickness of the characters. Negative numbers indicate thinner
characters. Positive numbers indicate thicker characters. Recognition
performance will improve for positive numbers, but noise will increase,
causing instability.
Larger values eliminate wide areas of noise. Small values eliminate nar-
row areas of noise.
If boundary correction is turned ON, dark areas at the edges of the mea-
surement region will be considered to be noise and removed from the
read candidates.
If rotation compensation is turned ON, the image will be compensated
for a −15° to 15° rotational variation. (This setting compensates for rota-
tional variations in the placement of the workpiece on the line, and not
for rotational variations in the characters themselves that result from
printing conditions.)
If slant compensation is turned ON, the image will be compensated for a
−20° to 20° slant variation. (This setting compensates for slant variations
in the placement of the workpiece on the line or in the printing mecha-
nism, and not for italic fonts.)
Sets the upper limit of the height of the region to treat as a hyphen or
other symbol.
Sets the lower limit of the height of the region to treat as a hyphen or
other symbol.
Sets the ratio of the height to the width of the detection character rectan-
gle to judge as thin characters (I, J, 1, :, and /).
Specify the width of the character to be read.
Specify the height of the character to be read.
If character strings with a variable number of characters are to be read,
specify variable.
