Scan Depth of Field (DOF)
DOF performance of the product was measured under the following conditions:
•
DOF is the distance from the top of scan engine to the barcode
•
23 ° C (73 ° F), 0 ~ 10K lux
•
Clear, high quality barcodes
Note: If the barcode is not aligned well with the scan engine, reading time and depth of field (DOF) will be
affected and the device performance will be decreased.
