1.9 - Targeting and Reading Techniques
The CR3 utilizes digital camera technology to take a picture of a symbol. Once an image is captured, the
CR3 utilizes advanced decoding algorithms to extract data from the captured image.
The CR3 is available as a palm-held unit or users may purchase a handle (available in various types).
The palm held unit features left and right triggers. These triggers may be programmed to perform various
features. The reader is shipped with the left trigger and right trigger functioning as a decode symbol
command.
Each handle has a trigger on the grip. The two triggers on the top of the unit also work when the handle is
attached.
To read a symbol with the CR3:
1.
The CR3 features omnidirectional decoding. Center the symbol in any orientation within
the laser dot aiming pattern (fi gure 1.15).
Note: The CR3 can read a symbol that is not centered; however, the CR3 performs best
when a code is centered. If two (2) bar codes are with the imagers decode zone, the CR3
will decode the symbol closest to the center of the aiming dot.
2.
The CR3 was developed to decode both very small 2-dimensional symbols and larger
1-dimensional symbols. The unit has an innovative dual fi eld decode zone. The CR3 DECODES
BOTH ZONES SIMULTANEOUSLY. The unit has a lens focused on a near-fi eld for
smaller codes (optimal focal point is 4 inches) and one lens focused on a far-fi eld
for larger codes (optimal focal point 9 inches). To read smaller symbols move the CR3
closer to the symbol. To read larger symbols move the unit farther away from the symbol.
The entire CR3 decode zone varies between two (2”) and twenty (20+”) or more inches.
