6.0 PCS Analysis
PCS scanning (overview)
This section is an overview of PCS (print contrast signal)
analysis.
When a successful scan is made, the
“Good Read” LED
will illuminate and a crisp chirp or beep sound will be
emitted.
Excellent results can be obtained when the auto-optic
scan head is used properly. Make sure the bottom clear
plastic plate of the scanner is flat against the surface to
be scanned. This will assure the proper scanning angle.
In addition to the data analysis screens you will also get
a PCS analysis screen:
PCS 87% Req 75%
Rmn 03% eRmx 90%
The top row of the display shows the calculated
PCS.
“Req” is the minimum PCS required for the
particular symbology.
The bottom row shows the minimum and maximum
reflectance of the elements in the symbol.
eRmx = maximum space reflectance
(light)
Rmn = minimum bar reflectance (dark)
Note:
The PCS is calculated as follows:
PCS = Rmx
