FH/FZ5 Processing Item Function Reference Manual
*1: Read mode: Only displayed in DPM mode.
*2: Read mode: Displayed if it is standard, the code type is DM and "Code quality display" is selected.
*3: Read mode: Displayed if it is standard, the code type is PDF417/Mi
croPDF417 and "Code quality display" is selected.
The display items checked in the result settings tab Grade display setting are displayed.
The grade code is displayed with a letter with numeric expression in parentheses, such as "A (4) to F (0)".
Key Points for Adjustment
Select the adjustment method referring to the following points.
When the measurement results are unstable
When codes cannot be read in correctly
RAP edge contrast
*3
A quality grade which shows the contrast of the start pattern, stop pattern, or specified line.
Verify the smallest contrast betw
een bar and space.
RAP modulation
*3
A quality grade which shows the brightness uniformity of the start pattern, stop pattern, or
specified line.
Verify the lowest edge contrast as ag
ainst to
the symbol contrast.
RAP defect
*3
A quality grade which shows the brightness uniformity of the start pattern, stop pattern, or
specified line.
Verify the uniformity of bri
ghtness betwe
en bar and space.
RAP decodability
*3
A quality grade which shows the printed accuracy of start pattern, stop pattern, or specified
lines.
A grade is high when the width of bar or sp
ace is cl
ose to the standard values.
RAP addionail
*3
A quality grade which shows whether there is a sufficient Quiet zone for start pattern, stop
pattern, or specified line.
RAP overall quality
*3
An overall quality grade for parts of the start pattern, stop pattern, or specified line.
Code word yield
*3
A grade quality which shows the efficiency to read the data by scanning the record.
An evaluation of the number of code is successful d
ecoded when repeat to scan the code.
Unused error correction
*3
A quality grade that shows the percentage of error corrected items.
A grade which is less errors is high grade.
Decodability
*3
A quality grade which shows the printed accuracy of codes parts.
A grade is high when the width of bar or space is close to the standard values.
Defect
*3
A quality grade which shows the uniformity of codes brightness.
Verify the uniformity of brightness betwe
en bar and space.
Modulation
*3
A quality grade which shows the uniformity of codes brightness.
Verify the lowest edge contrast as against to
the symbol contrast.
When the reading mode is DPM, a red circle is displayed on the cell whe
re the judgment of the white cell / black cell
is corrected in the image display area.
Parameter to be adjusted Remedy
Region setting Check whether there are codes to read i
n the measurement region.
Measurement parameter
Check if the settings, such as "Code type", "Code color", "Code length", and "Mirror setting",
are specified correctly.
T
imeout Check to make sure that the specified time is not too short.
