completion time is greatly been extended, you can carry out

5. Noun explanation of barcode density and depth of
field of code reading
Barcode density is the minimum distance between
white or black bars of the codes. Reading code depth of
field refers to the effective reading code range of one certain
density barcode, if you exceed the range of reading code, it
will not sensitive to read code or you can’t read
Take the first as example, 4mil (0.1mm)
，
it refers that,
the range of scanning gun window away from codes is about
5mm-60mm when scanning the codes which spacing is
0.1mm. If beyond the range, the code reading will not have
a good effect.
A qualified scanning gun can read from 4mil high
density barcode (or even 3mil) to 43mil super barcode, this
is also one important standard on barcode gun quality test.
Our scanning gun is improved in the circuit and the optical
system, all model scanning guns can reach this standard
100%, so the user doesn't have to match the different codes
with different scanning guns.
