Operation
Line scanner with oscillating mirror:
In the Percent Evaluation mode, the CLV490 behaves in the following manner:
–
in "Oscillating" mode (basic setting: oscillating with a fixed amplitude), the CLV490
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 CLV490 positions the scan line under the angle CW = 50 as
well.
–
in ”Fixed position” mode, however the scan line’s selected position remains unchanged.
1.
Choose the C
ODE
C
ONFIGURATION
tab.
2.
In the D
ECODER
section, choose S
TANDARD
.
3.
Perform a download to the CLV490.
To do so, click the S
TANDARD
option again with the right mouse button and choose
D
OWNLOAD
P
ARAMETER
in the context menu.
CLV-Setup copies the parameter to the CLV490 temporarily.
The CLV490 then operates with the standard decoder (until the CLV490 is switched
off).
4.
Click
in the toolbar.
The Terminal Emulator window is displayed. The CLV490 is in the Reading mode.
5.
In the D
EVICE
M
ODE
section, choose P
ERCENTAGE
E
VALUATION
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 CLV490 initiates the percentage
evaluation and outputs the reading results continuously. An example shows
.
