Counting direction of the reading angle (position of the bar code along the
scanning line)
The bar code scanner can scan and read several bar codes with every read. The location-
related reading diagnosis data is determined. The reading angle from the reading window
to the red scanning line of the scanning beam under which the middle of a bar code is de-
tected can be displayed as an RA (reading angle) value.
The determination of the RA value enables identical bar codes (code type, code length and
data contents) to be separated and the bar code data to be assigned to their position on the
object.
