If in Traditional P/F Test Mode. When in ANSI Grading Test Mode, the PCS
value shown is replaced with an ANSI letter grade or its numerical equivalent.
A symbol that consistently produces no beeping is either fatally out-of-spec or of
an unknown or unprogrammed bar code symbology.
The QC200's customer LCD display shows the user a complete synopsis of the
scan results. The information shown includes the decode of the symbol's
encoded characters (dot matrix characters in the middle of the LCD), the
symbology type (across the LCD top), the PCS or ANSI Grade (on the right when
in the Right Handed viewing orientation), an indication of bar growth/shrinkage
(small arrows to the extreme left of the LCD when in the Right Handed viewing
orientation) and in what parameter any error may have occurred (the key words
DIM, REF and/or FMT will light just to the left of the symbol decode, when in the
Right Handed viewing orientation).
If the encoded message in a bar code symbol exceeds 12 characters, the right
most character of the display will be a "right arrow" (>). In that case, pressing the
Scroll[<>] Button will "scroll" the encoded message and allow the remainder of
the message, in 11 character portion, to be viewed.
As mentioned above, uniform bar growth or shrinkage is displayed by a vertical
series of "arrows" on the LCD. One "arrow" will remain lit to indicate the average
bar width error in relation to traditional print tolerance allowances. When
centered between the "+" and "-" on the label, the bar growth/shrinkage is at a
minimum. As the arrow position moves toward the "-", increasing amount of
shrinkage is seen. Conversely, a move toward the "+" indicates bar growth.
When the arrow directly across from either the "+" or "-" is lit, traditional bar width
tolerances have been exceeded. There are seven arrows in the scale.
With each test scan of a symbol, the QC200 also indicates the sample's pass/fail
status with a characteristic "beep" pattern. One long beep with ONE short
indicates that the symbol passes the appropriate battery of tests. One long beep
with THREE short beeps indicates that it fails in some regard. Thus pass/fail
testing proceeds by simply scanning symbols and listening for a triple beep.
Upon any failure, the LCD indicates the parameter area where the failure
occurred. These areas are indicated by a three-letter abbreviation.
DIM = a DIMENSIONAL parameter error
REF = a REFLECTANCE (contrast) parameter error
FMT = a FORMAT parameter error
In a symbol with multiple errors, you will have more than one of the above
indicators lit. Exact details of the failure can be obtained by following the
procedures in the section that follows.
