The maximum value of an identifier is 100. If the value is lower (one- or two-digit number),
the leading blanks will be filled with spaces. If the D
ISPLAY
CONTROL
CODE
function is activated,
a space is displayed as <SPC>. The identifiers mean:
www = Number of successful readings ("Good reads")
xxx
= Number of successful decoding processes (with misinterpretations)
yyy
= Number of successful indentifications of a start or stop character (depending on
the scan direction)
zzz
= Number of readings carried out (the CLP 100 carries out 100 readings each in
the diagnosis mode)
Error-free reading and decoding of a bar code would thus have the following form:
<STX>Data/100/100/100/100<ETX>.
A reading with some failed decodings has, for example, the following form:
<STX>Data/<SPC>67/<SPC>67/100/100<ETX>.
If the CLP 100 has only recognized the start character, it transfers a question mark instead
of the data string:
<STX>?/<SPC><SPC>0/<SPC><SPC>0/100/100<ETX>.

shows further examples of reading results in the diagnosis mode:
