Percentage evaluation
In the Percentage evaluation mode, the quality of the reading function is assessed (no con-
veyor movement).
The CLX performs 100 scans in the free running mode and evaluates the reading quality. It
outputs the reading result continuously every 2 s via the terminal interface. The reading re-
sults can be displayed in the terminal emulator of CLV-Setup. The standard decoder has to
be set temporarily for the percentage evaluation.
The Percentage evaluation mode can be called up via V
IEW
in the menu bar or via the termi-
nal emulator.

– with event-controlled focus control the distance configuration that corresponds to the
reading distance of the object (default setting: no. 1, focus position F1 = 1 200 mm).
8.
Confirm the dialog box with OK.
The ”Device Ready” LED is extinguished. The CLX initiates the percentage evaluation

in the Terminal Emulator window. An example of this can be seen in
The ”Read Result” LED also provides information on the reading quality:
–
The LED is extinguished if reading quality is < 30%
–
The LED blinks twice per second if the reading quality is 30% ... 70%
–
The LED blinks five times per second if the reading quality is 70% ... 90%
–
The LED is lit continuously if the reading quality is > 90%
