Choose the appropriate distance configuration for the reading distance:
– with autofocus mode the distance configuration no. 1
– 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).

in the Terminal Emulator window.
Note
In default setting, the CLX operates in the autofocus mode "Minimum distance“. As a result,
the CLX focuses on the object that is nearest in Percentage Evaluation mode. The view on
the object with the scan line must be unobstructed, i. e. any other objects must not protude
into the autofocus space. If they do so, the autofocus mode "Differential background“ must
be selected. Alternatively a fixed focus position can be set.
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 % to 70 %
–
The LED blinks five times per second if the reading quality is 70 % to 90 %
–
The LED is lit continuously if the reading quality is > 90 %
