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 – Rmn

Rmx

1 2 ... 24 25 26 27 28 29 30 31 32 33 34 ... 83 84
