3. Output of reading result: No Read
The structure of the reading result for No Read is identical for 2-D codes and bar codes.
TT=_235 ms MG=_69 % n=_0
no code!
with:
1st line:
TT
= Reading interval time
MG
= Long-term mean value of identification quality
n
= Number of recognized code labels
2nd line:
no code
= No code found!
Triggering the reading pulse via the Terminal Emulator
In the default setting, the “Sensor 1“ switching input is the trigger source of the reading
pulse. The reading pulse can also be triggered directly via the terminal emulator of CLV
Setup for test purposes. To do so, a different trigger source must be selected temporarily
in the ICR.

reading area size at this reading distance: 40 mm x 32 mm (1.58 in x 1.26 in).
Note
To read a bar code, proceed as described in
