Step 2 — Determine Optimum Position
1. Position the reader in front of the symbol.
• High Resolution Option: 2.75 inches for near field or 4.5
inches for far field.
• Standard Resolution Option: 4 inches for near field and 9
inches for far field.
2. Determine the optimum read position by triggering at different
distances and angles.
3. To speed up decoding, try enabling near field or far field only.
(Both fields are enabled by default.)
In general, if the symbol element size is less than 0.010” (0.025 mm), enable near field
to a focal point. If more than 0.010” (0.025 mm), try the far field focal point. Also, if
symbols are placed closely together, you may want to use near field to lower the risk
of reading the wrong symbol.
See Trigger and Button Programming on page 3-7 for the configuration symbols
that correspond to these settings.
Other factors to consider:
• Use Both Fields for applications in which symbols may vary significantly in size
and distance from reader.
• On Quadrus models, try Fixed Mode for even quicker decodes for symbols with
consistent size and presentation (see Select Adaptive or Fixed Mode on page 3-5).
• For a more advanced setup, see Trigger Optimization on page 7-7.
