d. Filter Unprintable Characters

• Filter non printable characters are the used to filter the character

that not in the ASCII table.

• Those unprintable characters will be filter out from the barcode,

and display the rest barcode in system.

e. Ignore Failures

• Ignore Failures is used to ignore the barcode failure to show in

Inspection Summary list.

• This feature enabled will always treat the barcode as pass even

the it is Barcode0.

f. Flipped

• Tick to enable inspection for flipped

g. Acceptable Barcode Length

• used to set the maximum and minimum barcode length that

accepted as pass barcode

• The minimum barcode length able set to 1 and maximum

barcode length set to 128.

h. Image Plane

• Select the one that having best contrast among the Polarity Marking and

background.

i. Invert

• Used to invert the greyscale of the barcode from dark to bright and vise

versa.

j. Threshold Mode

❖ Fixed - Used when Barcode and background having good contrast.

❖ Dynamic - Used when Barcode and background having low contrast.

k. Threshold Count

• Threshold count is used to inspect the barcode with a constant inspection

range which threshold count is 17 as default value.

• When threshold count set to 17, the barcode will be decoded for 17 times

in a range of different grayscale level.

I. Median Filter

• This setting is use to remove the white dots (Noise)

m. Encoding Type

• Encoding Type is the barcode formats that able to support.

• Supported Encoding type as below:

❖ Codebar

❖ Code 39

❖ Code 93

❖ Code 128

❖ EAN 8

❖ EAN 132/5 Industrial

❖ 2/5 Interleaved

❖ All

n. Zoom Factor

• Zoom factor is used to set the inspection size of the barcode.

• When Zoom factor set to 0.5 (50% of original barcode size)
