Percentage Evaluation
In Percentage Evaluation mode, the quality of the reading of codes which are brought stat-
ically into the field of view of the ICR845-2 is assessed (no conveyor movement).
The ICR845-2 records repeatedly sets of images (each with 10 images) in the Free running
mode and evalutes the repeated recognising of the same code in sequential images. It out-
puts the reading result continuously via the auxiliary interface. The reading results can be
displayed in the Terminal Emulator of CLV-Setup. The "Result 1" and "Result 2" switching
outputs do not become live in the Percentage evaluation mode.
Important
The data communication of the auxiliary interface can also be routed via the Ethernet inter-
face. The seriel auxiliary interface (RS 232) will then become disabled. See
Chapter 5.5.5

Calling Percentage Evaluation for 2D codes:
The Percentage Evaluation mode can be called up by choosing V
IEW
in the menu bar or via
the Terminal Emulator.

The red illumination field (pulsed) appears repeatedly all 2 s.
The ICR845-2 initiates the percentage evaluation and outputs the reading results con-
tinuously.

)
in the field of view (no con-
veyor movement during reading!)
Required reading distance from reading window / resulting field of view:
ICR845-2C (Mid Range):
115 mm / 44 mm x 28 mm
(4.53 in / 1.73 in x 1.1 in)
4.
Monitor the reading results in the window of the Terminal Emulator.
