At present, DRK125A barcode detector is widely used in barcode quality inspection departments, medical industry, printing enterprises, production enterprises, commercial systems, postal systems, warehousing and logistics systems and other fields. The DRK125A barcode detector is a barcode quality inspection instrument that integrates photoelectric technology and computer technology. It implements national and international standards and can perform hierarchical inspections on the printing quality of barcode symbols. It can not only be used as a detector to analyze the printing quality of bar code symbols, but also can be used as a bar code data collector and a common bar code reader. 1. Product function ⑴ Automatically distinguish the code system of the bar code to be read, and the bar code symbols can be read from the front and back directions. ⑵ It can detect EAN-13, EAN-8, UPC-A, UPC-E, interleaved 25 bar codes, ITF bar codes, 128 bar codes, 39 bar codes, Kodeba bar codes and other code systems. ⑶ Automatically select the appropriate measuring aperture, and provide the detection data according to the bar code classification detection method. ⑷ Single scan or N scans (maximum 10 scans) can be selected. When N scans are selected, the average symbol level of N scans of the bar code can be obtained. ⑸ Can store no less than 10,000 EAN-13 barcode symbols for a single test result. ⑹ Chinese and English operation menu and result display. ⑺ With RS-232 communication interface, it can be connected to a printer to print the test results. ⑻ U disk can be used to export the inspection data (share the USB interface with the CCD reader for inspection) ⑼ With automatic/manual shutdown function, power saving sleep and automatic shutdown time can be set. ⑽ Low voltage warning, when the battery of the tester is about to run out, the tester will automatically send out a low-voltage warning with a sound of "Beep Ÿ" every 13 to 15 seconds. ⑾ Three ways of power supply are allowed: 4 AA alkaline batteries (random configuration)/dedicated external DC stabilized power supply (random configuration)/4 NiMH 5 rechargeable batteries (configured by the user). 2.

The use and storage conditions of the detector Conditions of Use: ⑴ Use environment: clean, less dust, no vibration and electromagnetic interference. Do not place the detector under direct strong light, do not place the instrument near water sources and heaters, and do not hit the detector (especially the CCD reader) with other objects. ⑵ Ambient temperature: 10～40 ℃. Environmental humidity: 30%~80% RH. ⑶ Power supply: 4 AA alkaline batteries (random configuration) / dedicated external DC stabilized power supply (random configuration) / 4 AA Ni-MH rechargeable batteries (configured by the user). ⑷ Barcode under test: The surface is clean, free of dust, oil and debris. Tip: The ambient temperature and humidity for the detector given above are the ambient temperature and humidity conditions for the detector to work normally. The environment, temperature, humidity, and lighting for bar code detection should meet the relevant requirements of GB/T18348. Storage conditions: ⑴ Storage temperature: 5～50 ℃ ⑵ Storage humidity: 10%~90% RH
