产品的 DOF 性能按以下条件进行测量:
产品的 DOF 性能按以下条件进行测量:
DOF performance of the product was measured under the following conditions:
• DOF 是指从扫描引擎顶端到条码的距离
• 23 °C(73 °F),0 ~ 10K lux
• 清晰、高质量的条形码
• DOF is the distance from the top of scan engine to the barcode
• DOF 是指从扫描引擎顶端到条码的距离
• 23 °C(73 °F),0 ~ 10K lux
• 清晰、高质量的条形码
• DOF is the distance from the top of scan engine to the barcode
•
23 °C (73 °F), 0 ~ 10K lux
• Clear, high quality barcodes
注意:若条形码没有正对扫描引擎,读取时间和景深(DOF)会受影响而降低设备性能。
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.
