Operation
Line scanner with oscillating mirror:
In the Percent Evaluation mode, the CLV behaves in the following manner:
–
in "Oscillating" mode (basic setting: oscillating with a fixed amplitude), the CLV shuts off
oscillation and positions the scan line under the angle CW = 50 (corresponds to a
deflection angle below 105
°
). This position cannot be altered.
–
in "One-Shot" mode, the CLV positions the scan line under the angle CW = 50 as well.
–
in ”Fixed position” mode, however the scan line’s selected position remains unchanged.

CLV-Setup copies the parameter to the CLV temporarily.
The CLV then operates with the standard decoder (until the CLV is switched off).

The dialog box for choosing the distance configuration is then displayed.
6.
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 (47.3 in)).
7.
Confirm the dialog box with OK.
The ”Device Ready” LED is extinguished. The CLV initiates the percentage evaluation
and outputs the reading results continuously. An example shows

8.
Present the bar code pattern from
and monitor the reading results
in the Terminal Emulator window.
