READING FEATURES

For correct functioning, the PackTrack™ operating mode requires a calibration just after the
installation of the scanners. This operation is absolutely necessary to make the scanner
recognize its position in space. Thus, a fixed reference system is required.
PackTrack™ uses a right-handed reference system (right hand with thumb = X axis;
forefinger = Y axis; middle finger = Z axis) where the axis X coincides with the PS line, the Y
axis coincides with the conveyor direction and the Z axis is oriented upwards from the
conveyor (see figure below).
This coordinate system is absolute for the reading station, i.e. is valid for all the scanners
independently from their position or orientation with respect to the conveyor.
Three barcodes are placed along the scanline. For each of them, three coordinates are
shown.
