Quick Check® 600/800 Series User’s Guide
For your convenience, the display option feature called “LEDs” allows you to
select ISO/IEC test criteria yet have the LEDs display bar growth rather than ISO/
IEC pass/fail grade. Refer to
"Changing the Output Options" on page 3-12
for
additional information.
If you set the verifier to use traditional pass/fail test criteria, the color of each
LEDs is always the same (first is red, second is yellow, third is green, fourth is
yellow, fifth is red). After a scan, one or two of the LEDs flash to indicate the
amount of growth or shrinkage. The following table correlates the LED color and
the percent tolerance used.
For example, if you scan a UPC symbol at 100% magnification and the yellow
LED on the left center flashes, it indicates that the tested symbol has used
approximately 2 mil (2.0 to 3.0 mil [0.002” to 0.003”]) of the total tolerance (± 4
mil [0.004”]) and that the symbol’s bars are too narrow.
If you set the verifier to use ISO/IEC methods to calculate the grade, the color of
the LEDs will vary. After a scan, one of the LEDs flashes to indicate the scan
grade (ISO/IEC Grade A, B, C or D). For example, if you selected ISO/IEC
Grade C as passing and obtained a scan grade of A, the A LED flashes to
indicate the scan grade the symbol received. In this case, the A, B and C LEDs
will be green to indicate that all three grades are acceptable.
Audio Sounds
The audio signal sounds to indicate the bar code symbol’s status to a
battery of tests:
•
One long beep followed by one short beep indicates a passing grade.
•
One long beep followed by three short beeps indicates a failing grade.
You can easily and quickly perform pass/fail testing by scanning symbols and
listening for a set of triple beeps to indicate failure and then review the display for
specific information.
