Product Description:Select barcode scanner before scanning equipment to understand several key technical parameters, and
then depending on the application requirements, the control of these parameters to select a suitable device.
Resolution
For bar code scanning system, the resolution is detected correctly read the most narrow width characters, English is the MINIMALBARWIDTH ( abbreviated as MBW). Select the device, not the device of braided rate the higher the better, but rather should be used depending on the application to select the density barcode scanner with the corresponding resolution . Use, if the selected resolution of the device is too high, a stain on the character bar, deinking and other impact on the system will be more serious.
Scan Depth
Scan depth refers to the premise of ensuring reliable reading, bar code scanning head allowed to leave the surface of the distance and close to the bar code scanner to the nearest point of the surface of the difference between the distance, which is the effective working range of the bar code scanner . Some bar code scanning equipment is not given in the technical indicators scanning depth of field indicators, but scanning distance given that first allowed to leave the bar code scanning the surface of the shortest distance .
Scan width (SCANWIDTH)
Scan width indicator refers to the distance given scan the scanning beam can read the value of the physical length of the barcode information .
Scan speed (SCANSPEED)
Scanning speed is the unit of time on the track scanning beam scanning the scan frequency .
A recognition rate
A recognition rate represents the first scan, the number of tags read with the ratio of the total number of scanning labels . For example, if each read a bar code labels to be scanned twice, a recognition rate of 50%. From a practical point of view, of course, hope that can be accessed through each scan, but unfortunately, due to a variety of factors, requires a recognition rate of 100% is impossible.
It should be noted that: a recognition rate of this test is only applicable to handheld indicator light pen scanning means of identification . If the laser scanning method, the beam scanning the bar code label frequencies up to hundreds of times per second, the signal obtained by scanning is repeated.
Ber
Error rate is a reflection of a machine readable identification tag system error condition is extremely important test indicators . Bit error rate is equal to the number of error identification and recognition of the ratio of the total number . For a bar code system, the bit error rate is more than a recognition rate more serious problems .
