code with total width of 3 inches is to be analyzed in a beam length of 6 inches
and the SV model being used performs a minimum of 100 scans/analyses per
second. Maximum speed of travel is (6 –3)inches /.050 seconds = 60 inches per
second in ladder direction.
Setting Ladder Mode Scanning Length Using ScanView
Software
The distance and location in the laser beam where a bar code is scanned
sometimes must be tuned (programmed) for a particular ladder mode
application. In general, the wider the length, the faster the bar codes can travel.
In some cases, a narrower scan length is required to mask an adjacent code so
only one code at a time is scanned. Instructions for using ScanView software to
program the scanning length is provided in
"SVScanner/Verifier Setup
Procedure" on page 4-13
.
Calibration
Calibration is required if any reflectance calculation (e.g., symbol contrast, Rmin,
PCS) is used in the application. It is recommended to calibrate the unit in any
case during initial setup to ensure the scanning distance and orientation is within
device limits. A calibration symbol is supplied with each SV unit as a standard
component. Store this symbol in a clean location.
The SV Series can be calibrated using either of the two following procedures:
Procedure 1
1. Remove all bar codes from the laser beam path.
2. Place the supplied calibration symbol in the laser beam in the same position
(distance and angle) as the labels to be verified will be scanned.
3. Press and hold the RESET button on the SV unit until the Calibration LED
begins to flash.
4. Release the RESET button immediately after the Calibration LED begins
flashing.
If calibration is successful, the laser beam will go off and the Calibration LED will
go off.
5. Remove the calibration symbol from the beam path, and press the RESET
button until the beam turns on. The SV unit is now ready to operate.
If calibration is unsuccessful, the Calibration LED will be either on steadily or
flashing. In this case, repeat the calibration procedure.
Procedure 2
1. Place the supplied calibration symbol in the laser beam in the same position
(distance and angle) as the labels to be verified will be scanned.
