Quick Check® 600/800 Series User’s Guide 4 - 15
Check Character
A check character in a symbol may be mandated by a bar code symbology
specification, by you, by both or not at all. The display reflects the requirement
and the result, either CkChr Checks if it passes or Check Character Fails if it fails.
If you do not set the unit to test for a check character, the message NO Check
Character appears. If the check character is bad, a message indicating that
appears.
Symbol Type
The symbol type refers to differences in symbol formats used in various
applications. That is, the same symbol used in different applications may have
a different length or a unique data or application identifier.
When you set the verifier to an application, the unit attempts to identify the
symbol type. For example, if an AIAG Code 39 symbol is six or fewer numeric
characters with a data identifier of Q, it is a “quantity” symbol. If the symbol is
nine or fewer alphanumeric characters with a data identifier of S, it is a “serial
number” symbol.
Chapter 8, Using a Quick Check 800 Verifier lists the symbol types and error
messages. If an application does not have a unique symbol format, the unit will
simply display the symbology.

Reviewing Messages
Errors can result from a variety of causes. They can result from errors in
dimensional, reflectance or format parameters generically or based on an
application. An example of a generic (symbology) error message that may
appear after scanning a symbol is “BAD QuietZon.” This message indicates that
there is insufficient quiet zone width.
