Mounting the CLV490
1.
Prepare the base for mounting the bracket as described in
.
2.
Place the object containing the bar code within the reading field of the CLV490 (in the
position at which it is to be read) with the conveyor belt switched off.
3.
Align the CLV490 with the bar code (in accordance with the scanning method) in such
a way that
– with the line scanner the back of the device with the LEDs is almost parallel with the
bar code surface,
– with the line scanner with oscillating mirror, the broad side wall (back of the oscillating
mirror) is almost parallel with the bar code surface
All of the possible reading angles must be taken into consideration (see
).
4.
If it is relevant for the evaluation, note the count direction of the reading angle and code
angle (see
).
5.
Mount the CLV490 bracket on the base.
