1.9 - Targeting and Reading Techniques
The CR2 utilizes digital camera technology to take a picture of a symbol. Once an image is captured, the CR2 utilizes
advanced decoding algorithms to extract data from the captured image.
The CR2 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 CR2:
1.
The CR2 features omnidirectional decoding. Center the symbol in any orientation within
the laser dot aiming pattern (Figure 1.24).
Note: The CR2 can read a symbol that is not centered; however the CR2 performs best when a code is centered.
If two (2) bar codes are within the imager’s decode zone, the CR2 will decode the symbol closest to the center of
the aiming dot.
2.
The CR2 was developed to decode both very small 2-dimensional symbols and larger 1-dimensional symbols.
The unit has an innovative dual field decode zone. The CR2
DECODES BOTH ZONES SIMULTANEOUSLY. The
unit has a lens focused on a near-field for smaller codes (optimal focal point is 4 inches) and one lens focused
on a far-field for larger codes (optimal focal point 9 inches). To read smaller symbols move the CR2 closer to the
symbol. To read larger symbols move the unit farther away from the symbol. The entire CR2 decode zone varies
between two (2”) and twenty (20+”) or more inches.
3.
Hold the CR2 still -
DO NOT SWIPE OR MOVE THE READER. Press the trigger until the CR2 beeps, indicating
the code has been successfully decoded.
4.
The reader may be optimized to your specific environment by scanning codes in Chapter 2.
