Release Time:2020-07-21

How to use the two-dimensional bar code scanning gun? Hongxing Yongli Company has sorted out customer cases for similar problems: Shenzhen * * Manufacturing Factory has explained the on-site use test of the two-dimensional bar code scanning gun, hoping to help all new and old customers. The physical photo of the bar code is as follows:

For new users to purchase, read the following: guide for purchasing barcode scanning guns. according to the above customer case barcode, the XYL-1920 of barcode scanning guns that can scan and change barcode and text barcode is selected.

the correct scanning method of scanning gun:

The two-dimensional code should be placed flat on the desktop and kept flat. The inner inclined plane of the scanning gun shall be parallel to the two-dimensional code, as shown in the following figure:

About scanning distance:

After actual testing, it is recommended that the scanning distance be 8cm to 12cm, and customers can also debug a most suitable distance according to their own site environment. Generally, the scanning distance is related to the size of the two-dimensional code, the depth of field of the scanning gun, and the precision parameters. Different two-dimensional codes and non-configured two-dimensional guns have different scanning distances. If you are not a professional, do not know how to calculate the recognition distance, or do not understand the optical picture on the manual, you can directly test yourself and adjust to an optimal recognition distance.

　　

 

For a larger two-dimensional code, the scanning distance is too close, and the recognition ability may decrease. Generally speaking, for the same two-dimensional code scanning gun, when identifying a two-dimensional code with a large area, the distance is relatively farther, and when identifying a two-dimensional code with a small area, the distance is relatively pulled in.
